Answer:
$38.64
Explanation:
$46
30% discount:
30% of $46 = 0.3 × $46 = $13.80
Price after 30% coupon:
$46 - $13.80 = $32.20
20% fee:
20% of $32.80 = 0.2 × $13.80 = $6.44
Price after coupon and fee:
#32.20 + $6.44 = $38.64
Answer: $38.64
Quick way:
30% discount means you pay 70% (= 0.7) of original price.
20% fee means you pay 120% (= 1.2) of price.
$46 × 0.7 × 1.2 = $38.64
