Answer:
1: -3
2: She gives him $3 per week
3: 18
4: How much money she initially borrowed
5: y = -3x + 18
<u>Answer:</u>
Total paid = $717.3
Finance charge = $167.3
<u>Step-by-step explanation:</u>
The cost price of mountain bike = $550
The down payment on bike = 75% of $550 = 0.75 * 550 = $412.5
We know that he will make 12 payments of $25.40 each so total monthly payments = 12 * 25.40 = $304.8
The total amount paid = Down payment + Total monthly payments = $412.5 + $304.8 = $717.3
The finance charge = Total amount paid - Cost price = $717.3 - $550 = $167.3
The answer would be 23/41
