Sam deposited money into an account in which interest is compounded semiannually at a rate of 1.25%. How much did she deposit if the total amount in her account after 7 years was $4115.73, and she made no other deposits or withdrawals?

3771.94

Step-by-step explanation:

(1+0.0125/2)^14 = 1.091145

You get the 2 from the semiannually

and the 14 came from doing 7 x 2

and you move the decimal 1.25% to the left twice, to get 0.0125

Then you take $4115.73 and divide that by 1.091145

4115.73/1.091145 = 3771.94

and I took the test and got it right!

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
