I believe you will earn $960? I’m not completely sure that that is correct since I did it in my head.
The correct answer is C) -15.
Anyways, I hope you have a wonderful evening :)
This will be false because that’s not the average winter temperatures in 45 states
Let p = pictures only
let f = pictures with frames
p + f = 100
5p + 10f = 875
Solve for one variable in the first equation then plug into the second
p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75
75 pictures with frames were sold
