The difference between the amounts of interest Marcus and Gianna paid for their car loan is $50
<h3>The amount and simple interest</h3>
The formula for calculating the amount on simple interest is given as:
A = P + I
I = PRT
A = PRT + P
Given the following paramteers
A = 10000(0.047)(5) + 100000
A = 2350 + 10000
A = 12350
For Gianna
A = 10000(0.045)(5) + 100000
A = 2250 + 10000
A = 12250
Difference = 12350 - 12250 = $50
Hence the difference between the amounts of interest Marcus and Gianna paid for their car loan is $50
