please select the best answer from the choices provided

a
b

Explanation:

Step1: Calculate pre-tax subtotal

$\$16.89 + (5 \times \$1.19) + \$3.68 + (2 \times \$1.88) = \$16.89 + \$5.95 + \$3.68 + \$3.76 = \$30.28$

Step2: Calculate 5% sales tax

$\$30.28 \times 0.05 = \$1.514$

Step3: Total after tax, before coupons

$\$30.28 + \$1.514 = \$31.794$

Step4: Calculate total coupon value

$2 \times \$0.45 = \$0.90$

Step5: Final amount owed

$\$31.794 - \$0.90 = \$30.894 \approx \$30.89$

Step6: Compare paid vs owed

$\$30.89 - \$30.89 = 0$

Answer:

b. paid the correct amount
