Erica and 4 friends are going out for pizza for dinner. They split one pizza and 5 small drinks. The pizza costs $13.00. They spend a total of $20.50. Find the cost of one small drink. Define the variable, write and solve an equation, and answer the question.

Answer 1

to find the cost of a small drink, you might want to:

• subtract the decimals

total cost : $20.50

cost of pizza :$13.00.

cost of one small drink : total cost - cost of pizza

: $20.50 - $13.00.

: 20.50

- 13.00

: 07. 50

: $ 7.50
