Answer: The value of x- 2y is a.
.
Step-by-step explanation:
Given: x and y are two positive real numbers such that
and
.
Consider ![(x-2y)^2=x^2-2(x)(2y)+(2y)^2\ \ \ [(a+b)^2=(a^2-2ab+b^2)]](https://tex.z-dn.net/?f=%28x-2y%29%5E2%3Dx%5E2-2%28x%29%282y%29%2B%282y%29%5E2%5C%20%5C%20%5C%20%5B%28a%2Bb%29%5E2%3D%28a%5E2-2ab%2Bb%5E2%29%5D)


Put
and
, we get


Taking square root on both sides , we get'

Hence, the value of x- 2y is a.
.
If 532,475 warranties were given, it means that 532,475
warranties were sold. The gross profit should be, 532,475 * $830 = $441954250.
But then, this would still be subtracted with 12% of the warranties since they
gave it back to the customers. Hence,
Profit = $441954250 – 0.12(532,475)($225)
Profit = $427,577,425
Answer:
