Will mark brainliest!

Option B: Difference between their amount of interest is $157.94.

Solution:

Mary's loan:

Principal = $10000, Rate of interest = 6.50%, Time = 4 years

n = 1 (compounded annually)

A = $12864.66

Interest = Amount - Principal

             = $12864.66 -  $10000

Interest = $2864.66

Kyle's loan:

Principal = $10000, Rate of interest = 4.50%, Time = 6 years

n = 1 (compounded annually)

A = $13022.60

Interest = Amount - Principal

             = $13022.60 -  $10000

Interest = $3022.60

Difference between their interest

            = $3022.60 - $2864.66

            = $157.94

The difference between the amount of interest Mary and Kyle paid for their loans is $157.94.
