P(x)=R(x)-C(x) Given that: R(x)=2.5x and C(x)=0.5x+3 Then, P(x)=2.5x-(0.5x+3) P(x)=2x-3 thus for profit of $99, the number of units will be found as follows: 99=2x-3 solving for x we get: 102=2x x=56 units
The answer is C.. because if you do 95x100 you get 950 and then you need to do 2x10 and you get 20, so then you subtract 20 from 950 and you will get $930
