Question

Erin is buying produce at a store. She buys C cucumbers at $0.99 each and A apples $0.79 each. What does the expression 0.99c+0.79a represent?

Answer 1

This expression could represent two situations.

One, if you knew the number of cucumbers and apples bought, you could find out how much money was spent on them altogether.

Two, if you know the total amount of money spent, you could solve for c and a to find out how many cucumbers and apples were bought.
