If Randall parents do not charge him any interest, then all 4 scenarios are not possible, because:

A - $850 - (5 x $94)  =$380 in debt.

B - $850 - (6 x $94)  =$286 in debt.

C - $850 - (7 x $94)  =$192 in debt.

D - $850 - (8 x $94)  =$98   in debt.

The answer is C.  All debt scenarios, except for C, show an average payment greater than $94

 

He promised to repay the loan by giving his parents at least $94 from his paycheck each week.

Haha Ginger,

This was an exercise in reading the question properly and you failed. :))

"which of the following is not a possible scenario "

 

 

Randall borrowed $850 from his parents to make some repairs on his car. He promised to repay the loan y giving his parents at least $94 from his paycheck each week. Assumming Randall sticks to his promise, which of the following is not a possible scenario for the amount of debt Randall has remaining?

 

850/94 = 9.0425531914893617     so it will take a maximum of 9 and a bit weeks to repay.

minimum repaid

1 week           94                       maximum  left to be repaid             850-94 = 756

2 weeks        188                       maximum left to be repaid             756-94 = 662

3  weeks       282                       maximum  left to be repaid             662-94 = 568

4 weeks        376                       maximum  left to be repaid            568-94 = 474

5 weeks        376+94 = 470      maximum   left to be repaid            474-94 = 380

6 weeks        470+94 = 564      maximum   left to be repaid            380-94 = 286

7 weeks        564+94 = 658      maximum   left to be repaid            286-94 = 192

8 weeks        658+94 = 752      maximum   left to be repaid            192-94 = 98

9 weeks        752+94 = 846      maximum   left to be repaid            98-94 = 4

 

 

A. After 5 weeks, Randall is $125 in debt.       yes this is possible

B. After 6 weeks, Randall is $175 in sdebt.     yes possible

C. After 7 weeks, Randall is $225 in debt.       not possible 

D. After 8 weeks, Randall is $75 in debt.         not possible

 

So if Randall pays his parents back as aggreed, scenario C and D are not possible

This could have been done a lot quicker but I wanted to show you what was happening.
