Answer:
36.36
Step-by-step explanation:
We can express 10% as a decimal by multiplying it by (1/100), resulting in 0.1. Therefore, adding 0.1 of the original price, or x, to the price will result in 40, so x+0.1*x=40
= 1.1x
Dividing both sides by 1.1, we get that x, or the original price, is $36.36 (approximately).
