original price=A
A x 25/100=$31.14
simplify 25/100 = 1/4
A x 1/4=$31.14
A/4=$31.14
multiply both sides by 4
A=$124.56

He bought if for $31.14 and this is 25% off the original price.
Let the original price be P.

25% of original price P = (25/100) P = 0.25P.
We have to take this off from P. = P - 0.25P = 0.75P

0.75P = 31.14
P = 31.14 / 0.75 = 41.52 Use your calculator.

Hence original price = $ 41. 52.
