which is the best estimate of the amount of interest you will save if you take the loan for 2 years instead of 3 years?

SOLUTION
The amount to be saved will be
( $157 for 3 years ) - ( $226 for 2 years )
= ( $ 157 x 36 months) - ( $ 226 x 24 months )
= $ 5652 - $ 5424
= $ 228
= $ 220 .......... OPTION C
