Question

Teresa is going to the grocery store to buy some snacks. A bag of chips is $2. 50 each and a bag of pretzels is $3. 25 each. Write an equation that represents the number of bags of chips, c, and bags of pretzels, p, Teresa bought if she spent a total of $15. *

Answer 1

2.50c + 3.25p = 15

Explanation:

2.50 times the number of bags of chips bought equals the total cost of chips bought.

3.25 times the number of bags of pretzels bought equals the total cost of pretzels bought.

Added together equals the total amount of money Teresa spent on chips AND pretzels. The question tells us that the total amount of money equals $15. So the equation would be: 2.50c + 3.25p = 15

(cost of chips)(number of bags of chips) + (cost of pretzels)(number of bags of pretzels) = amount spent
