(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

On the first day, shoes in a shop were sold for $30 each. On the second day, the price of a shoe was reduced and the number of shoes sold on the second day increased by 50% while the money collected increased by 25%. Find the price of a shoe sold on the second day.

3. The attempt at a solution

well, I tried using an algebraic solution but got stuck. I used two unknowns, where

x=number of shoes sold on the first day

y=amount reduced for the price of a shoe sold on the second day.

I only managed to yield one equation from the problem which was not enough obviously,

amount collected on saturday:

[tex] 1.5x(30-y)=30x\times1.25 [/tex]

please help, I must be missing another equation somewhere. Also, the final answer should be $25.
