I think the answer is $6.30 , because you have to add. So 2.80 multiple by 2 would be 5.6 and after that you divide 2.80 by 4 since .25 it's a quarter of the whole so that gives you 6.3.
x / x^-4 = x ^(1 - -4) = x^5
y^2 / y^-6 = y^(2 - -6) = y^8
So the answer is x^5 / y^8
or x x^4 / y^2y^6 which is the second answer choice

You spent 9 dollars. why? because your neighbor spent 3 times more than you, which means you spent 1/3 of what he spent. so just multiply by 1/3 to get 9.
this can also be modeled by an equation. 3x = 27
divide 3 on both sides to get
x = 9
