Given
Clark made four of his truck payments late and was fined for late fees
total change that his savings from late fees was $40
Find out how much was one late fee.
To proof
Clark made four of his truck payments late
Total late fee = $ 40

4x = 40
solving the above equation
we get
x = $10
thus clark one late fee be $ 10
Hence proved
