Question

you purchase 3 packs of batteries at $11.99/ pack. you have a coupon for 10% off and the sales tax is 7%. how much is the total cost of your purchase? (1 point) $38.49 $32.37 $34.64 $30.11

Explanation:

Step1: Calculate pre-coupon total cost

$3 \times 11.99 = 35.97$

Step2: Apply 10% discount

$35.97 \times (1 - 0.10) = 35.97 \times 0.90 = 32.373$

Step3: Apply 7% sales tax

$32.373 \times (1 + 0.07) = 32.373 \times 1.07 \approx 34.64$

Answer:

$34.64$ (Option C: $34.64$)
