A company uses the formula T = 581s+150p to determine the total cost to purchase s computers and p printers. Which formula can be used to determine the number of printers purchased, given the total cost, t, and the number of computers purchased?

Answer: p = T/150 - 3.88s

Step-by-step explanation:

Hi, to answer this question we have to solve the equation for p.

T = 581s+150p

T - 581s = 150p

(T - 581s) / 150 = p

T/150 - 3.88s = p

p = T/150 - 3.88s

For example if the total cost is $600 and the number of computers is 1:

p = 600/150-3.88 (1)

p=4-3.88

p = 0.12 per printer
