Question

Hey I kinda need some help with this could u help?

Answer 1

`x = 13 ~~ \text{and}~~ y= 10`

Explanation:

`~~~~~~2.31 * 10^x = 2200 * 1.05 * 10^y\\\\\implies 2.31 * 10^x = 2310 * 10^y\\\\\implies (10^x)/(10^y) = (2310)/(2.31)\\\\\implies 10^(x-y)=1000\\\\\implies 10^(x-y) = 10^3\\\\\implies x - y = 3`

`\text{If x = 13 and y = 10 then the difference will be 3.}`
