You worked as a lifeguard this summer and earned an extra $3,000. You decided to deposit that amount into your savings account.

Nataly [62]

Answer:

The correct answer is $3300 for simple interest and $3312.24 for compound interest.

Step-by-step explanation:

Income as working as a lifeguard = $3000

We deposit the money in a bank which offers 2% interest annually for a period of 5 years.

Case 1 : Calculating simple interest for the given situation.

Amount after 5 years = 3000 + 3000 × 2 × 5 × $\frac{1}{100}$ = $ ( 3000 + 300) = $3300.

Case 2 : Calculating compound interest for the given situation.

Amount after 5 years = 3000 × $(1 + \frac{2}{100} ) ^{5}$ = $ 3312.24.

Thus the amount after 5 years amount simply is $3000 and compoundly is $3312.24
