In order to find the final price of the shoes, we need to calculate each discount separately. Since the initial cost of the shoes is $120, we need to first find the cost after the 20% discount. If the shoes are discounted 20%, then we can find the cost by multiplying the original amount by 80%, or 0.8: $120 x 0.80 = $96.00. Since the customer also has an additional 5% off with the coupon, we can then take the new total, $96.00, and multiply by 95%, or 0.95, to get the final cost: $96.00 x 0.95 = $91.20.
