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?
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.
Determine how much more Jim paid at site A than at site B
Jim paid $2.25 more at site A than at site B
Given:
Site A:
y = 0.85x
Site B:
y = 0.40x
where,
y = total amount paid
x = number of photos
If Jim provides 5 photos for each site
Site A:
y = 0.8x
y = 0.85(5)
y = $4.25
Site B:
y = 0.40x
y = 0.40(5)
y = $2
Site A - site B
= $4.25 - $2
= $2.25
Therefore, Jim paid $2.25 more at site A than at site B
