A discount voucher offering 15% off is used to pay a bill. After using the voucher, the bill is reduced to £36.72.

Elena-2011 [213]

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.

-10x - 135 = 117 + 2x<br> A. 25<br> B. -18<br> C. -21<br> D. 22 <br> Helps pls

Lina20 [59]

Answer:

C

Step-by-step explanation:

Add 10x to both sides:

-10x - 135 = 117 + 2x

-10x - 135 + 10x = 117 + 2x + 10x

-135 = 117 + 12x

Subtract 117 from both sides:

-135 - 117 = 117 + 12x - 117

-252 = 12x

Divide both sides by 12:

$\frac{-252}{12} = \frac{12x}{12}$

-21 = x

So the answer is C.

Hope this helps!
