ANSWER
- The expression represents the cost of c cucumbers and a apples
- $0.89 represents the cost of one cucumber
Step-by-step explanation
Erin is buying produce at a store.
She buys c cucumbers at $0.89 each.
She buys a apples at $0.99 each.
Assumiing we wanted to find a compact way of representing the amount of money that Erin spent, we would have to find the cost of the c cucumbers and the a apples.
Let us do this:
Since we know that each cucumber costs $0.89, we have that c cucumbers will cost:
$0.89 * c = $0.89c
In the same manner, since one apple costs $0.99, we have that a apples will cost:
$0.99 * c = $0.99a
Therefore, the total amount that Erin will spend will be the sum of both:
A = 0.89c + 0.99a
Therefore, the expression represents the total cost of the c cucumbers and a apples or the total amount spent by Erin.
$0.89 represents the cost of one cucumber (we have been told that already)
