With 9% price increase, the  original selling price of the business is $192.66

A business sometimes need to increase the price of their products, to increase the profit margin or for other reasons.

Let:

p = original price

r = percentage of price increase

Then,

new price = original price + percentage of price increase x original price

new price = p + r. p = (1 + r) p

Data from the problem:

new price = $210

r = 9% = 0.09

Plug these parameters into the equation:

new price = (1 + r) p

210 = (1 + 0.09)p

p = 210/1.09 = 192.66
