Rose and dennis each open a savings account at the same time. rose invests $2,600 in an account yielding 4.1% simple interest, and dennis invests $2200 in an account yielding 5.7% simple interest. after nine years, who has the greater total amount of money, and how much greater is it?

Rose has the greater total amount of money. It is $3559.4 - $3328.6 = $230.8 greater.

Step-by-step explanation:

In simple Interest, the future value (A) is calculated as follows:

A = P*( 1 + r*t )

where:

P is the principal

r is the annual interest rate

t is the number of years between payments

For Rose:

A = 2600*( 1 + 0.041*9 ) = $3559.4

For Dennis:

A = 2200*( 1 + 0.057*9 ) = $3328.6

Rose has the greater total amount of money. It is $3559.4 - $3328.6 = $230.8 greater
