Answer:
$200
Step-by-step explanation:
1. if you take $5 for each car wash then you take total of the cars they washed and then you times 40x5=200 then you subtract the total amount of money they paid for the supplies. Which was $32 and 200-32=168.
2. No they will not because if you go 5,10,15,20,25,30,35,40,45,50,60,65,70,75,80,85,90,95,100,105,110,115,120,125,130,135,140,145,150,155,160,165,170,175,180,185,190,195,200.
