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?
$1.15
$1.35
$2.15
$2.25

A way to represent the amount of money that site A requires for \(x\) number of photos is \(y = $0.85x\).
We already know the equation for site B, which is \(y = $0.40x\).
If \(x = 5\), substitute it back into the equation for site A we will get...? And for site B we will get...?
OpenStudy (volleyballlover55):
i do y=0.40(5) ?
OpenStudy (calculusxy):
Yes.

OpenStudy (volleyballlover55):
ok..
y=2
OpenStudy (calculusxy):
Correct. What about for site A?
OpenStudy (volleyballlover55):
whats the equation for site A again?
OpenStudy (calculusxy):
\(y = $0.85x\)
OpenStudy (volleyballlover55):
ok.. and the x is 5?

OpenStudy (volleyballlover55):
ok..
x=4.25
OpenStudy (calculusxy):
Correct. Now find the difference between the values.
OpenStudy (volleyballlover55):
how?
OpenStudy (calculusxy):
Subtract.
\(4.25 - 2\)
