Answer 1

Answer:

b.

$7.68

now to use the coupon

20.39 * 20%

20.39*.20= 4.08 off

23.99-16.31 = 7.68

He saved 7.68

Answer 2

Answer:

Answer: B ) $7.68

Step-by-step explanation:

$23.99 * 0.15 = $3.5985

$23.99 - $3.5985 = $20.3915

With more 20% off:

$20.3915 * 0.2 = $4.0743

$3.5958 + $4.0783 = $7.6768 ≈ $7.68
