What is simple interest?

Simple interest can be defined as a form of interest in which the percent rate is applied on the same principal for a given period of time.

Given that,

Money deposited by Monica is $200 at simple interest of 3.7%.

Money deposited by Paul is $300 at simple interest of 2.9%.

The expression to calculate simple interest is given as,

(P × r × t)/100

Substitute the corresponding values to obtain the simple interest for both cases as follows,

Interest gained by Monica is (200 × 3.7 × 1)/100 = $7.4.

Interest gained by Paul is (300 × 2.9 × 1)/100 = $8.7.

Hence, monica is not correct as the interest earned by Paul is greater than that of monica.
