Question

Sian bought TV in January sales which had been reduced by 20 per cent. If she paid £290 for it, what was the original price?

Answer 1

x=original price.
20%=20/100=0.2
We can suggest the next equation to solve this problem:

x-0.2x=290

We solve this equation:
x-0.2x=290
0.8x=290
x=290/0.8
x=362.5

Answer: the original price was £362.5.
