Answer: After 4 years, the six friends will have a total of $1,858.24.

The total amount that is being placed into the account is $1,500. 250 x 6 = 1500

To calculate the interest, you have to multiply it by 1.055 4 times. This is because 5.5% is being added on each year and the interest is compounded.

A simple equation for this would be:  1500(1.055)^4 = 1858.24
