Question

ron pays .08 to make a copy. She is considering buy a photocopy machine that is on sale for $250. including tax. How many copies would Ron have to make in the copy shop for her cost to equal the purchase price of the copy machine she is considering to purchase

Answer 1

The trick is writing down exactly what the question is asking you.

 

how many copies, at .08 ea = purchase price

 

let x be the number of copies.  x times 0.08 will be the price for all these copies and the problem says the purchase price is 250:

x(.08) = 250

 

divide both sides by .08 to isolate x

 

x = 250 / .08

 

 

x = 3125
