Mr.Shea saved $2,500 in April. His monthly salary is Twice the amount he saved in April. In May, he saved a certain amount of money.He spent $4,200 more than the amount he saved. How much did he save in May.

April savings  2500
Salary  5000
May saving  x
Amount spent in May = x + 4200
x + 4200 = 5000
x = 800 
here is the answer.
lets say X is the saved money in May.
He spend 4200 more than X. It meant X+4200 is the money that he spent.
So, X + (X+4200) needs to be 5000.
Therefore, X=400. He saved 400 dollars in May 
800

He saved $2,500 in April.
He earned $5,000 in May.
Thus he had a total of $7,500
Total spent in May  $4,200 + $2,500+X
X= Amount saved in May
Thus total = Amount spent + Amount saved
Thus total = $4,200 + #2,500 + X + X
$7,500 = $4,200 + $2,500 + 2X
Solve for X
$7,500 = $6,700 + 2X
2X = $800
X = $400 
my brain hurts

400

9200 you poopybutt

This question was written by a moron. Where does it say that he could only spend his monthly salary? What happened to the $2500 he saved last month, or the rest of the money he has in the bank? He could've saved any amount from $15000. Not to mention the bigger problem. If he spent $4200 more than he "saved" then the real answer is $0. He didn't really save anything.
