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
