Emily bought 3 shirts for $12.50 each and a pair of shorts for $20. She had a coupon for $3 off her purchase, before sales tax. Sales tax is 6%. How much did Emily pay for the clothes after the coupon and sales tax?
A
$54.50
B
$57.77
C
$60.50
D
$64.13
To calculate how much Emily paid for the clothes after the coupon and sales tax, we need to follow these steps:
Step 1: Calculate the total cost of the 3 shirts
Since each shirt cost $12.50 and she bought 3, the total cost of the shirts is 12.50 * 3 = $37.50.
Step 2: Calculate the total cost before the coupon
Adding the cost of the shirts and the shorts, the total cost before the coupon is 37.50 + 20 = $57.50.
Step 3: Apply the coupon
Subtracting the coupon of $3 from the total cost before the coupon, we get 57.50 - 3 = $54.50.
Step 4: Calculate the sales tax
To calculate the sales tax, we need to multiply the total cost after the coupon by the sales tax rate and add it to the total cost after the coupon.
Sales tax = 6% = 0.06 (decimal form)
Sales tax amount = 54.50 * 0.06 = $3.27
Step 5: Calculate the final cost
Adding the sales tax to the total cost after the coupon, we get 54.50 + 3.27 = $57.77.
Therefore, Emily paid $57.77 for the clothes after the coupon and sales tax.
The correct answer is B, $57.77.
