PLZ HELP!

Jeff provides photos for two online sites: site A and site B.

Site A pays $0.65 for every photo Jeff 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 = 0.60x.

How much more was Jeff paid at site A than at site B, if he provided five photos for each site?

Answer 1

$0.25

Explanation:

Site A pays ...

... $0.65 × 5 = $3.25

Site B pays ...

... y = 0.60·5 = 3.00 . . . dollars

Site A pays more by ...

... $3.25 - 3.00 = $0.25

_____

You can also look at the difference in unit rates. Site A pays $0.65 per photo, while site B pays $0.60 per photo, a difference of $0.65 - 0.60 = $0.05 per photo. Then 5 photos will be worth $0.05 × 5 = $0.25 more at Site A.
