Answer: 10.22 is what he will save.
Step-by-step explanation: 18 3/4 x 2.80=51.1
51.1 x 20%=10.22
Answer:
$102.48
Step-by-step explanation:
183 * 2.80 = 512.4 (cost before discount)
512.4 * 0.20 = 102.48
It's 20% off 100% of an item, and when calculating problems like this, use 1 to represent 100%. So you multiply the cost by 0.2 to get 20% of the cost.
