Question

What proportion can be used to determine the sale price of a pair of shoes that are priced at $210.00 and on sale for 45% off?

Answer 1

if the pair of shoes are on sale for 45% off, what you really pay is the 55% of the product.

write the proportion taking into account that $210.00 is the 100%

`(210.00)/(100)=(x)/(55)`
