Answer:
cost of the refrigerator = $873 
$34 will be more than $50 each payment
Step-by-step explanation:
Given data 
principal = $1008
interest = $135
installment = 12 
to find out 
the cash cost of the refrigerator and  How much more that $50 will each payment 
Solution
cost of the refrigerator = principal - interest      ...........1
put the value principal and interest in equation 1 
cost of the refrigerator = $1008 - $135
cost of the refrigerator = $873 
we have installment 12 for $1008 i.e. 
each installment = $1008 / 12 
each installment = $84
for last part $84 each installment so we can say $84 - $50 = $34
$34 will be more than $50 each payment
