Step-by-step explanation: If you do the math 299 divided by 45 you will get 40 so now add 40 to 299 you will get $339 minus 50 cents will be 25 so $339.25 would be the original price of the bike.
First, you have to take the discount percentage and divide it by 100 to get an actual number. In this case, you would get 0.45. Then you would subtract 1 from 0.45, giving you 0.55. Then you put it into an equation like this (op meaning original price):
op = 299.75 / 0.55
If you divide 299.75 by 0.55, it gives you $545.00.
