An additive inverse is the value you can add to a given value such that the sum is "0"..
Your answer is choice A 18xy + (-18xy) = 0 Since these are like terms.. the key here is understanding that like terms must have the same exact variables raised to the exact same powers. We can add like terms. We cannot add unlike terms.
So, to solve this, we use this equation: 3700 + 0.05(3700) But, if we want to make it shorter: 1.05(3700) Now you just multiply(you may want to use a calculator) 1.05(3700) = 3885 She will pay $3885
