Let
x-------> Leila 's profit
y------> Jo's profit
we know that
----------> equation ![1](https://tex.z-dn.net/?f=%201%20)
For ![y=\$60](https://tex.z-dn.net/?f=%20y%3D%5C%2460)
<u>Find the value of x</u>
Substitute the value of y in the equation ![1](https://tex.z-dn.net/?f=%201%20)
![\frac{x}{60} =\frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B60%7D%20%3D%5Cfrac%7B3%7D%7B4%7D)
![x=60*\frac{3}{4}](https://tex.z-dn.net/?f=x%3D60%2A%5Cfrac%7B3%7D%7B4%7D)
![x=\$45](https://tex.z-dn.net/?f=%20x%3D%5C%2445)
therefore
<u>the answer is</u>
Leila make
in profit
