Terrence deposited $5,720 in a bank account with interest rate
6%. How much interest was
earned in 4 years?

I don’t have a calculator with me but if you put this in you can get the full answer. To work out the value of a number after a percentage increase, change it to a decimal (so increase by 6% is 1.06 if it was decrease it would be 0.94 etc) and multiply this by the original price and have the decimal multiplier to the power of how many times it increases by that percentage so 4 years would be to the power of 4 so
5720 x 1.06^4 in the calculator will get you the answer

Well let’s see here we need nuts and more nuts and probably more nuts so why not‍♂️

Iknow one of the answers is a and maybe b but not 100% sure about b
