Jeremy and randell are brothers and each are trying to raise money for summer camp. to jeremy raise money, his parents told him he could wash each of their cars once a week for $20.00 each. he has already earned $640.00. the football camp that he wants to attend costs $1,469.00. to randell raise money, his parents told him he could mow the grass for them and both sets of grandparents once every 2 weeks and earn $28.00 for each lawn he mows. he has already earned $728.00. the lacrosse camp that he wants to attend costs $1,701.00. if jeremy and randell each earn enough money to attend the camps of their choice, then from this point on ? needs to complete ? more chores than ? .

So since their are 2 cars to be washed each week, that's $40. each week(w for the variable) with the start of $640. so far the equation to that is, 640 + 40w=y. the end goal is $1,469. since he has already made 728, and  he gets to mow the lawn for 3 people every 2 weeks for $28. each lawn, he would be getting $84 every 2 weeks. adding the ending to the equation would make it 640 + 728  + 40w = 1,469. now since washing cars is every week when mowing lawns is every 2 weeks, we need to change our equation to be, 80w + 1,368 + 84w= 1,469 + 1,701. the next step is to simplify, 164w + 1,368= 3,170. now we solve.
3,170 - 1,368= 1,702.
164w = 1,702     1,702  / 164 = 11 weeks. hope this : )

I’m not positive but i think it’s none of your buisness

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
