Q:
The profit P (in dollars) from selling x calculators is P =25x-(10x+250). How many calculators are sold when the profits are $425?
Accepted Solution
A:
To solve this all you need to do is plug 425$ in for P.
425 = 25x - (10x + 250)
*Distribute the negative sign*
425 = 25x - 10x - 250
*Add 250 on each side*
675 = 25x - 10x
*Combine like terms*
675 = 15x
*Divide by 15*
x = 45
