Maria has $350, she spends 2/7 of her money & invests the rest for 2 years at 5% per year simple interest .How much money does Maria have at the...

Spendinfg of Maria = (2/7) of $350
= $100.

The rest of the money  invested = 350-100 =
$250.

The rate of interest  on investment =
5%.

The money after  she gets after 2 years is required to be
calculated.

We use the formula Interest amount =  PTR/100 where P =
amount invested , T = number of years, and R = rate of
interest.

Therefore the interst amount Maria gets after 2 years =
250*2*5/100 = $25.

So the amount Maria should get after 2 years =
Invested amount +Interest accrued = 250+25 = $275.
