Answer:
40,000 is 39,265 rounded to the nearest ten thousands
Step-by-step explanation:
Y - x = 154
let z = xy = x(154 + x) = x^2 + 154x
we need to find the minimum value of z
z' = 2x + 154 which = zero for minm or maxm value
x = -77 and y = 154 -77 = 77
so the 2 numbers are -77 and 77
6000 - 1800 = 4200
4200/4 = 1050
so she donated 25% to charity
