Jairo spent $40.18 on 3 music CDs.
Let’s solve for the original prices of each CDs.
=> The sales tax added is 2.33 dollars
=> 40.18 dollars – 2.33 dollars
=> 37.85 dollars
he used 1.00 dollar coupon during his purchase
=> 37.85 + 1.00 = 38.85 dollars
=> now, we need to divide this amount to 3 for 3 CDs
=> 38.85 / 3
=> 12.95
the cost of each CD is 12.95
