person(1) buys a basket of plural_form(fruit(1)) on sale for `\$DOLLARS` before tax. The sales tax is `SALES_TAX\%`. What is the total price person(1) pays for the basket of plural_form(fruit(1))?

`\$\` TOTAL_PRICE

To find the total price, first find the amount of sales tax paid by multiplying the sales tax by the original price of the basket of plural_form(fruit(1)).

`\blue{SALES_TAX\%} \times \green{$DOLLARS} = \text{?}`

Percent means "out of one hundred," so `\blue{SALES_TAX\%}` is equivalent to `\blue{\dfrac{SALES_TAX}{100}}` which is also equal to `\blue{SALES_TAX \div 100}`.

`\blue{SALES_TAX \div 100 = localeToFixed(SALES_TAX/100, 2)}`

To find the amount of sales tax that must be paid, multiply `\blue{localeToFixed(SALES_TAX/100, 2)}` by the original price.

`\blue{localeToFixed(SALES_TAX/100, 2)} \times \green{$DOLLARS} = \purple{$localeToFixed((SALES_TAX/100) * DOLLARS, 2)}`

To find the final price person(1) paid, add the sales tax you just found to the original price.

`\purple{$localeToFixed((SALES_TAX/100) * DOLLARS, 2)} + \green{$localeToFixed(DOLLARS, 2)} = $localeToFixed(TOTAL_PRICE, 2)`

If the sales tax in your city is `localeToFixed(TAX, 1)\%`, and an item costs `\$PRICE` before tax, how much tax would you pay on that item?

Round to the nearest hundredth or cent.

`\$\` TOTAL_TAX

To find the amount of sales tax you would pay, multiply the sales tax by the original price of the item.

`\blue{localeToFixed(TAX, 1)\%} \times \green{\$PRICE} = \text{?}`

Percent means "out of one hundred," so `\blue{localeToFixed(TAX, 1)\%}` is equivalent to `\blue{localeToFixed(TAX, 1) \div 100}`.

`\blue{localeToFixed(TAX, 1) \div 100 = localeToFixed(TAX / 100, 3)}`

To find the amount of sales tax that must be paid, multiply `\blue{localeToFixed(TAX / 100, 3)}` by the original price. Round to the nearest cent.

`\blue{localeToFixed(TAX/100, 3)} \times \green{\$PRICE} = \$localeToFixed(TOTAL_TAX, 2)`

person(1) bought a new clothing(1) at the store when they were having a `DISCOUNT\%` off sale. If the regular price of the clothing(1) was `\$PRICE`, how much did person(1) pay with the discount?

`\$\` DISCOUNT_PRICE

First, find the amount of the discount by multiplying the original price of the of the item by the discount.

`\blue{\$PRICE} \times \green{DISCOUNT\%} = \text{?}`

Percent means "out of one hundred," so `\green{DISCOUNT\%}` is equivalent to `\green{\dfrac{DISCOUNT}{100}}` which is also equal to `\green{DISCOUNT \div 100}`.

`\green{DISCOUNT \div 100 = localeToFixed(DISCOUNT/100, 2)}`

To find the amount of money saved, multiply `\green{localeToFixed(DISCOUNT/100, 2)}` by the original price.

`\green{localeToFixed(DISCOUNT/100, 2)} \times \blue{\$PRICE} = \purple{\$localeToFixed((DISCOUNT/100) * PRICE, 2)}`

To find the final price person(1) paid, subtract `\purple{\$localeToFixed((DISCOUNT/100) * PRICE, 2)}` from the original price.

`\blue{\$PRICE} - \purple{\$localeToFixed(DISCOUNT / 100 * PRICE, 2)} = $localeToFixed(DISCOUNT_PRICE, 2)`

The pizza(1) store is having a `DISCOUNT\%` off sale on all of its plural_form(pizza(1)). If the pizza(1) you want regularly costs `\$PRICE`, how much would you save with the discount?

`\$\` TOTAL_DISCOUNT

To find the amount saved with the discount, multiply the discount by the original price.

`\blue{DISCOUNT\%} \times \green{\$PRICE} = \text{?}`

Percent means "out of one hundred," so `\blue{DISCOUNT\%}` is equivalent to `\blue{\dfrac{DISCOUNT}{100}}` which is also equal to `\blue{DISCOUNT \div 100}`.

`\blue{DISCOUNT \div 100 = localeToFixed(DISCOUNT/100, 2)}`

To find the amount of money you saved, multiply `\blue{localeToFixed(DISCOUNT/100, 2)}` by the original price.

`\blue{localeToFixed(DISCOUNT/100, 2)} \times \green{\$PRICE} = \$localeToFixed(TOTAL_DISCOUNT, 2)`

person(1) {has {breakfast|lunch|dinner}|eats} at a {restaurant|cafe} and the cost of his meal is `\$BILL_FORMAT`. Because of the service, he wants to leave a `TIP_PERCENT\%` tip. What is his total bill including tip?

person(1) {has {breakfast|lunch|dinner}|eats} at a {restaurant|cafe} and the cost of her meal is `\$BILL_FORMAT`. Because of the service, she wants to leave a `TIP_PERCENT\%` tip. What is her total bill including tip?

`\$\` TOTAL

The tip amount is equal to `TIP_PERCENT\% \times \green{\$BILL_FORMAT}`.

We can find the tip by first calculating a `\purple{10\%}` tip and dividing it by two. and multiplying it by two. and a `\pink{5\%}` tip, and then adding those two numbers together.

To calculate a `\purple{10\%}` tip, move the decimal point in `\green{\$BILL_FORMAT}` one place to the left.

`\purple{10\%} \times \green{\$BILL_FORMAT} = \purple{\$TIP_TEN_PERCENT}`

To calculate a `\blue{5\%}` tip, divide the `\purple{10\%}` tip amount in half.

`\blue{5\%} \times \green{\$BILL_FORMAT} = \purple{\$TIP_TEN_PERCENT} \div 2 = \blue{\$TIP_FIVE_PERCENT}`.

To calculate a `\pink{5\%}` tip, divide the `\purple{10\%}` tip amount in half.

`\pink{5\%} \times \green{\$BILL_FORMAT} = \purple{\$TIP_TEN_PERCENT} \div 2 = \pink{\$TIP_FIVE_PERCENT}`.

To calculate a `\blue{20\%}` tip, multiply the `10\%` tip amount by two.

`\blue{20\%} \times \green{\$BILL_FORMAT} = \purple{\$TIP_TEN_PERCENT} \times 2 = \blue{\$TIP_AMOUNT_FORMAT}`.

Adding the two amounts together gives us `\purple{\$TIP_TEN_PERCENT} + \pink{\$TIP_FIVE_PERCENT} = \blue{\$TIP_AMOUNT_FORMAT}`.

The total bill is the cost of the meal plus the tip.

`\green{\$BILL_FORMAT} + \blue{\$TIP_AMOUNT_FORMAT} \purple{\$TIP_AMOUNT_FORMAT} = \$TOTAL_FORMAT`.
