A is accumulated amount investing after p principal for t years at and interest rate of r compounded anually k is times per year.
P=$1500, r= 7%, t=6
I will do the second, then you follow the same method to do the other two
A = 1500(1 + .07/4)^(5*4)
in the first and third assume that k = 1, that is keep the rate at .07 and .054
