Answer 1

3.

y ≥ $67x - $750
y ≤ $67x - $750
y ≥ $67x + $750
y ≤ $67x + $750

Robert borrowed $750 from his parents to make some repairs on his car. He promised to repay the loan by giving his parents at least $67 from his paycheck each week. Assuming Robert sticks to his promise, which of the following is not a possible scenario for the amount of debt Robert has remaining? (1 point)

After 5 weeks, Robert is $150 in debt.
After 6 weeks, Robert is $200 in debt.
After 7 weeks, Robert is $250 in debt.
After 8 weeks, Robert is $300 in debt.

Answer 2

Consider the minimum payment
Week interest paid loan (at most) (x = total loan - interest paid)
1 67 750 - 67 = 683
2 67 x 2 = 134 750 - 134 = 616
3 67 x 3 = 201 750 - 201 = 549
4 67 x 4 = 268 750 - 268 = 482
5 67 x 5 = 335 750 - 335 = 415
6 67 x 6 = 402 750 - 402 = 345
7 67 x 7 = 469 750 - 469 = 281
8 67 x 8 = 536 750 - 536 = 214

The amount of the loan can be less than x as he may pay more than 67 in any weeks. However, it cannot be greater than x as he keeps his promise to pay the minimum amount of 67. Can you get the answer now?

Answer 3

Hoped that helped. ^

Answer 4

3: B because it starts at -750 and increases at multiples of 67 every week

Answer 5

Wow yes thank you @HELP!!!!!!!!!!! and @StudyBlu. This is so very helpful. My teacher is out this week and I am homeschooled. This is so great :)

Answer 6

No problem (: im homeschooled to.

Answer 7

No problem :)

Answer 8

I'm not really sure on number 4 still.

Answer 9

It gets confusing when I try to connect the interests

Answer 10

I got that he'd be 225 dollars in debt but i did something wrong apparently

Answer 11

Well i think its A because its says he can pay his parents AT LEAST $67 a week so if he paid them the minimum of $67 in 5 weeks there is no possible way for him to owe $150

Answer 12

That does make sense. I keep searching in my lesson but I can't seem to find that example problem I did earlier. Grrrr. Ohwell.

Answer 13

Lol Good luck :)
