Answer:
$80
Step-by-step explanation:
Regular payment= $50 which is equivalent to 100%
Therefore, $50 = 100%
=> the customer has to pay 120%, so we must find the value of that extra 20%
=> 20% of $50 = 20/100×50
= $10
Therefore, late payment= $50 + $10 = $60
Total late payment= $60 + late fee
= $60 + $20
= $80
