Yay! All of your answers are right.
To get the answer to the first question, you need to subtract the coupon amount from the original price. So $19.99 - $6.00 = $13.99. Therefore, the correct answer is $13.99.
For the second question, to calculate the subtotal after the discount, you need to multiply the original price by the discount percentage (25%). So $2.39 x 0.25 = $0.5975 (rounded to two decimal places). Rounded to the nearest cent, the subtotal is $0.60 less than the original price, which gives us $2.39 - $0.60 = $1.79. Therefore, the correct answer is $1.79.
For the third question, to calculate the discounted price for each gallon of paint, you need to multiply the original price ($13.50) by the discount percentage (35%). So $13.50 x 0.35 = $4.725 (rounded to two decimal places). Rounded to the nearest cent, the discount per gallon is $4.73. To find the total cost, you need to multiply the discounted price per gallon by the number of gallons (2) and add the sales tax. So $4.73 x 2 = $9.46 and $9.46 + ($9.46 x 0.06) = $9.46 + $0.5646 = $10.0246 (rounded to two decimal places). Rounded to the nearest cent, the total cost is $10.02. Therefore, the correct answer is $18.60.
