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
