Step by step solution

01

Concept introduction

Compound interest : It's the addition of interest to the principal sum of loan.

02

Explanation of Solution for A

Given : P=$5,000,n=30years,r-5%,for A and4.75%forS

Using compound interest formulae for A,

A=P1+r100n

A=$50001+510030

A=$5,000(1+0.05)30

A=$5,000(1.05)30

A=5000×4.32

=$21,600

03

Explanation of Solution for S

Using compound interest formulae for S,

A=P(1+r100)n

A=$50001+4.7510030

A=$5000(1+0.0475)30

A=$5000(1.0475)30

A=$5000*4.02

=$20,118

04

Final answer

Hence, A have $1482($21,600-$20,118)more than S.
