There are four pairs (m,n) that work: (5,10), (6,6), (8,4), and (12,3).
Let x be the number of cars. We will find out how many cars you have to wash to make as much money as your friend:
10x - 25= 13x - 55 Add 25 on both sides and subtract 13x, also both sides:
3x = -30 Now divide both sides by -3:
x= 10 cars you have to wash.
<span><span>16<span>x^4</span></span>+<span>40<span>x^3</span></span></span>−<span>24<span>x^<span>2
That is it</span></span></span>
