Bill = X
Tip = Y = 12 % Bill = 12 * Bill /100
Total = Z = Bill + Tip = X + 12 * Bill / 100 = 112 * Bill /100 = 1.12 * Bill
Tip = 0.12 * Bill = $ 5.76 =>
Bill = $ 5.76 / 0.12 = $ 48 Bill amount before tip.
Total payment = 1.12 * Bill = $ 53.76
Tip = Y = 12 % Bill = 12 * Bill /100
Total = Z = Bill + Tip = X + 12 * Bill / 100 = 112 * Bill /100 = 1.12 * Bill
Tip = 0.12 * Bill = $ 5.76 =>
Bill = $ 5.76 / 0.12 = $ 48 Bill amount before tip.
Total payment = 1.12 * Bill = $ 53.76
