In 2015, the price of a business math text rose to $150. This is 7% more than the 2014 price. What was the old selling price?

Question

I don't understand how to figure this out

Answer 1

1.07o = 150

1.07o = 150/1.07

o = 140.19

Answer 2

p + 0.07p = $150

1.07p = 150

 

Can you solve for p and answer?
