Amanda is making pillows for her sofa, the fabric that she likes costs $45 per yard. amanda waits until
she has a 40% off coupon! how much [including tax] will amanda pay for 58 inches of material? the tax
rate is 5.1%.

Well 58 inches is 4 feet, so Amanda has to purchase 2 yards of fabric. So this brings her to $90. If you multiply 90 by 40%, and then subtract that number from 90, you have 54. Multipy 54 by the sales tax and then add that number to 54. So Amanda will have to pay $56.75. Hope this helps, have a nice day :)
