Answer:
Hours
Step-by-step explanation:
Jake is being paid $15 an hour, not per child.
Say he has five children, three stay for one hour, two stay for two hours. If he's getting paid per hour, then he'd earn $105. But, if he gets paid per child he'd only make $75 dollars.
But since it says that he gets paid per HOUR, it would be proportional to how much money he makes.
Using formula of difference of two squares a^2 -b^2 =(a-b)(a+b) we get
49p^2 -64y^2 = (7p -8y)(7p +8y)
and
1 - 25x^2 = (1 -5x)(1 +5x)
