Mrs. taylor bought a water tube to pull behind her boat. the tube cost $87.00 and 9% sales tax was added at the register .mrs. taylor gave the cashier five $20 bills. how much change should she have received

To find the sales tax you’d need to find 9% of 87. You find this by using this template, x%/100%=y/z, x being the sales tax, y being 9% in cash, and z being the 87 dollars. You multiply the x value by the z value, (9 X 87=783) and then divide that product by 100%. This gives you the sales tax of 7.83, and when you add that to 87 you get $94.83. Subtract that from the 5 20 dollar bills ($100) and you are left with $5.27 change.
