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

`TOTAL`

The tip amount is equal to

.`TIP_PERCENT`\% \times \$`BILL_FORMAT`

We can find the tip by first calculating a `10\%`

tip and then dividing that number by two. and then multiplying that number by two. and a `5\%`

tip, and then adding those two numbers together.

To calculate a `10\%`

tip, move the decimal point in `\$`

one place to the left.`BILL_FORMAT`

`10\%`

`\times \$`

= `BILL_FORMAT``\$`

`TIP_TEN_PERCENT`

To calculate a `5\%`

tip, divide the `10\%`

tip amount in half.

`5\%`

`\times \$`

`BILL_FORMAT` = `\$`

`TIP_TEN_PERCENT`` \div 2 = `

`\$`

.`TIP_FIVE_PERCENT`

To calculate a `20\%`

tip, multiply the `10\%`

tip amount by two.

`20\%`

`\times \$`

= `BILL_FORMAT``\$`

`TIP_TEN_PERCENT`` \times 2 = `

`\$`

.`TIP_AMOUNT_FORMAT`

Adding the two amounts together gives us `\$`

+ `TIP_TEN_PERCENT``\$`

`TIP_FIVE_PERCENT` =` \$`

.`TIP_AMOUNT_FORMAT`

The cost of the meal plus the amount of the tip will equal the total bill amount.

`\$`

`BILL_FORMAT` + \$`TIP_AMOUNT_FORMAT` = `\$`

.`TOTAL_FORMAT`

The total cost of the bill is `\$`
