A copy center offers its customers two different pricing plans for black and white photocopies of 8.5 in. by 11 in. pages. Customers can either pay $0.08 per page or pay $7.50 for a discount card that lowers the cost to $0.05 per page. Write and solve an equation to find the number of photocopies for which the cost of each plan is the same.

Question

campbell_st · Answer

well the equations are, letting x be the number of copies

Cost = 0.08x

and 

Cost = 0.05x + 7.50

so now you can equate the equations to find what number of copies will give the same cost

0.08x = 0.05x + 7.50

now just solve for x
