You are purchasing office supplies. because of the volume of your orders your company receives 15% off all purchases. you buy a case of paper for $24.95 and a toner refill at $35.99. you find discontinued ink for $49.95 at 50% off. the local sales tax is 4.5%. what do you spend

The correct answer is:

$76.32.

Explanation:

Adding together the paper for $24.95 and the toner refill for $35.99 gives us

24.95+35.99 = $60.94

50% off of the ink that is normally $49.95 gives us

0.5(49.95) = 24.975 = $24.98

Together this gives us

$60.94+$24.98 = $85.92

Taking 15% off of this leaves us with 100-15 = 85% of the cost; this gives us

0.85(85.92) = $73.032 ≈ $73.03

Adding 4.5% tax means we spend 100% of our $73.03 plus an additional 4.5%; 100+4.5 = 104.5%; 104.5% = 104.5/100 = 1.045

This gives us

1.045(73.03) = $76.32
