Answer:
6.12%
Explanation:
Calculation for How does our decision depend on the interest rate at which we can invest our funds
Present value = 6000-3060
Present value = 2940
Future value = Present value+Present Value*Numver of month* Rate of interest/ 100
3000 = 2940+2940*4/12*R/100
60 = 2940*4/12*R/100
60*12/4 = 2940*R/100
180 = 2940*R/100
180/2940 = R/100
0.061224 = R/100
Rate = 6.1224
Therefore How does our decision depend on the interest rate at which we can invest our funds is 6.1224
