Answer:

Money decrease = $58.21

Total Bill = $159.79

Step-by-step explanation:

Starting Value = $218

Percent Decrease = 26.7%

End Value = x

Value Decrease = $218 - x

x = 1(218) - 0.267(21.8)

x = 0.733(218)

x = 159.794 ≈ $159.79

Money Decrease = $218 - $159.79 = $58.21

Total Bill = $159.79
