Sheila has been making regular quarterly payments of $200 into an account for 15 years that is compounded annually. she now has $12,000. what is the annual interest rate of her account?

50.6

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
