Question

at a shoe store shoes are one third of their original price the sale price of a pair of gym shoes is $ 15.50 write and solve an equation that could be used to find the original cost of the shoes

Answer 1

We will write an equation to find the original cost as follows:

$15.50=\frac{x}{3}$

And the general equation will be:

$y=\frac{x}{3}$

Here y is the price after discount and x the price without discount.

****

Since we have that the price is a third of the original, then the discounted price is found by multiplying the original value of the shoe times 1/3. After this operation takes place, the value we will obtain is the discounted prices [1/3 their original value].
