You deposited $125 in a savings account that earns a simple interest rate of 3.5% per year. You earned a total of $8.75 in interest. For how many years was your money in the account? The formula for simple interest in shown below.

$450 i think. hope this ☺

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
