I need help for this math problem

Question

At the local photography store, it costs $1.50 for the first print of a photograph and $0.50 for each additional print. Write an equation can be used to determine x, the number of maximum prints that can be purchased with $20.00?

Answer 1

Hi Juli,

The equation for your math problem can be written as follows:

$1.50 + $0.50x = $20

Since every additional photographic print costs $0.50, and we will need to determine how many additional photographs will need to be printed at that cost (when added to the $1.50 for the first photographic print) in order to amount to a total of $20, the variable x represents how many photographs will ultimately need to be printed to reach the $20 total price accordingly.
