Answer:
86 years after the $35,885 donation is made
Step-by-step explanation:
Let n be the total number of years.
Each year they sent $2500, so in n year they send 2500n dollars.
They sent $35,885 to start with, so after n years, they will have sent a total of
2500n + 35,885
We need to find the value of n for which 2500n + 35,885 exceeds $250,000.
2500n + 35,885 > 250,000
2500n > 214,115
n > 214,115/2500
n > 85.6
The first year after 85.6 years have passed is year 86.

Answer:
1.31, 0.19 to nearest hundredth.
Step-by-step explanation:
1/x + 1/(x - 1) = 4
Multiply through by x(x - 1):-
x - 1 + x = 4x(x - 1)
4x^2 - 4x = 2x - 1
4x^2 - 6x = -1
4(x^2 - 3.2 x) = -1
Completing the square:-
4 [ ( x - 3/4)^2 - 9/16] = -1
4(x - 3/4)^2 - 9/4 = -1
4(x - 3/4)^2 = 5/4
(x - 3/4)^2 = 5/16
x - 3/4 = +/- √5 / 4
x = √5 / 4 + 3/4 , -√5 / 4 + 3/4
= 1.31, 0.19 to nearest hundredth.
