Rudolph borrowed $650 from his parents to make some repairs on his car. he promised to repay the loan by giving his parents at least $76 from his paycheck each week. assuming rudolph sticks to his promise, which of the following is not a possible scenario for the amount of debt rudolph has remaining?

What you need to do is take 650 and subtract the number of weeks paid times $76.
So, if these are your options:
After 5 weeks, Rudolph is $285 in debt
After 6 weeks, Rudolph is $185 in debt
After 7 weeks, Rudolph is $100 in debt.
After 8 weeks, Rudolph is $40 in debt

I: 650 - (5*76) = 650 - 380 = 270 - impossible, because the number has to be higher than the one he is in debt (285)
II: 650 - (6*76) = 650 - 194 - possible
III: 650 - (7*76) = 650 - 118 - possible
IV: 650 - (8*76) = 650 - 608 = 42 - possible

The correct answer is A. After 5 weeks, Rudolph is $285 in debt 

A= r2 × 3.14 7x7 ↓ ↓ 49 × 3.14 = 153.86 → 153.9
