A bike is on sale for $170. This is 80% of the regular price. find the regular price

170-80%=136

i like it is $136 is the regular price

you can also try to add them

You need to do proportions.

For this, I am going to set the numerator to only having prices and the denominator to only have the percentages.

170/80 = x/100,

where x is the regular price of the shirt, and the 100 is there because the regular price is technically 100% of the price.

So then we do cross multiplication and solve for x.

170 (100) = 80x

17000 = 80x

212.5 = x

So the bike's regular price is $212.50
