After 2 years: 2217.72 After 5 years: 2589.52

Work Step by Step

2000, compounded quarterly, 5.2% 2 years: $A = P*(1+(r/n))^{nt}$ $A = 2000*(1+(.052/4))^{4*2}$ $A = 2000*(1+.013))^{4*2}$ $A = 2000*(1.013))^8$ $A = 2000*1.013^8$ $A = 2000*1.108857$ $A = 2217.714$ 5 years: $A = P*(1+(r/n))^{nt}$ $A = 2000*(1+(.052/4))^{5*4}$ $A = 2000*(1+.013))^{5*4}$ $A = 2000*(1.013))^{20}$ $A = 2000*1.013^{20}$ $A = 2000*1.2947589$ $A = 2589.52$
