Monica deposits ​$200 into a savings account that pays a simple interest rate of 3.9​%. Paul deposits ​$300 into a savings account that pays a simple interest rate of 3.2​%. Monica says that she will earn more interest in 1 year because her interest rate is higher. Is she​ correct? Justify your response.

Respuesta :

Answer: No, Monica is incorrect.  Paul will get more interest in 1 year.

Step-by-step explanation:

Formula: Simple interest : [tex]\dfrac{\text{principal x rate x time}}{100}[/tex]

Given: For Monica, Principal =$200, rate = 3.9%

Interest in 1 year = [tex]\dfrac{200\times3.9\times1}{100}=\$7.8[/tex]

For Paul, Principal =$300, rate = 3.2%

Interest in 1 year = [tex]\dfrac{300\times3.2\times1}{100}=\$9.6 > \$7.8[/tex]

Thus , Paul will get more interest in 1 year.

i.e. Monica is incorrect.
