Question

Jim provides photos for two online sites: site A and site B. Site A pays $0.85 for every photo Jim provides. The amount in dollars (y) site B pays as a function of the number of photos provided (x) is represented by the equation y = 0.40x. How much more was Jim paid at site A than at site B, if he provided five photos for each site?

Answer 1

We can use the same equation to figure out with only substituting the amount he was paid per photo.

Site A    y = $0.85x      =  $0.85(5)  =  $4.25
Site B    y = $0.40x      =  $0.40(5)  =  $2.00

We can see that Jim was paid $2.25 more at site A than Site B.
