We can use the is/of=p/100 method for this problem. Since it's 15% off, this would mean that the bill is 85% of what it was initially. Plug the values into the is/of=p/100 formula.
36.72/x = 85/100
Solve for x.
x=36.72/0.85
x=43.2
So, the bill was $43.20 before applying the voucher discount of 15% off.

Answer:
£43.20
Step-by-step explanation:
A discount voucher offering 15% off is used to pay a bill.
Let the original bill be x
After using the voucher of 15% off, the bill is reduced to £36.72
100 - 15 = 85
85% of the bill = £36.72
0.85x = £36.72
x = [tex]\frac{36.72}{0.85}[/tex]
x = 43.20
The bill was £43.20 before applying the voucher discount.
