Answer:
$5,170
Explanation:
If he chose intallment plan, his cost are as follows:
Down Payment = $3000
and
Monthly 390 for 48 months is $390 * 48 = $18720
Total Cost (with financing) = $3000 + $18,720 = $21,720
Without financing, he paid directly by cash for $16,550. That is much less than $21,720. How much did he save?
We subtract and find:
21,720 - 16,550 = $5,170
