Answer:
(D) 20%
Explanation:
The original price of the two items = $60 + $40 = $100
The discounted price of the two items = $60 + ($40 x 0.5) = $60 + $20 = $80
To find the percent discount he received off his total purchase, we need to divide the difference between the original price and the discounted price by the original price.
$100 - $80 = $20
$20 ÷ $100 = 0.2
0.2 = 20%
