A discount voucher offering 15% off is used to pay a bill. After using the voucher, the bill is reduced to £36.72. How much was the bill before applying the voucher discount?

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.

£43.2

Step-by-step explanation:

We minus 15 from 100 to get the percentage represented by 36.72

We are using 100 because it represents the total which is unknown

We cross multiple and get our answer

36.72=85%

X =100%

100×36.72÷85=43.2

i think asking google will you get the answer to that question

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
