Because I haven’t into math in 30 years, maybe you brainiacs can help me out with my son’s homework. Besides, I almost failed algebra.

Office Depot makes business cards for $2.25 and a box set up fee of $4.50. FedEx Office makes business cards for $1.75 a box plus a box set up fee of $6.00. How many boxes of business cards does each company make for the price to be equal?

Update: I re-learned how to combine variable. Thanks, everybody.
