Explanation:

The total amount earned after a given number of years can be expressed as;

A=P(1+r/n)^nt

where;

A=total amount earned

P=initial investment

r=annual interest

n=number of compounding periods in a year

t=number of years

Consider Jarom's;

P=$5,000

r=7%=7/100=0.07

n=2

t=(70-30)=40 years

replacing;

A=5,000(1+0.07/2)^(2×40)

A=5,000(1.035)^80

A=$78,378.6877

Jarom will have a total of $78,378.6877 by retirement

Consider Christina's total amount;

P=$5,000

r=7%=7/100=0.07

n=12

t=40

replacing;

A=5,000(1+0.07/12)^(12×40)

A=$81,557.057

Christina will have a total of $81,557.057 by retirement

Christina will have more than Jarom when the retire
