Oops, sorry the sheet is upside down!
As a grade 7 middle schooler, I often have to deal with crappily worded Maths sheets. Such as the one picture in the attatchment. There numerous ambiguities that I would like to have clarified with some smart people, to do with the wording of the sheet. If you help me, please state your level of education in Maths, so I can tear the out of my teacher if she tells me I'm wrong.
1. Dog Walking- The adverstisment says "3 times a week. 20 mins at $2 a session. Mon/Wed/Fri." I'm assuming that means that you can only work one session of 20 minutes for $2 a day, meaning that Kris and Carolyn would earn $12 a fortnight (unless they earn $2 each which is question number 2)
2. Their mother told them that they must work together. The only job that requires 2 people is car washing, so wouldn't it be reasonable to assume that the car washing employers are prepared to pay them $5 each? There is no mention on the Baby-Sitting advertisment that two people are needed, so presumably, Kris and Carolyn would get $11 every hour between them. Is this correct?
1. I was under the impression that this meant that all of their earnings are compiled together. So, they only earn $6 bucks for working 1 hour total every week.
2. No, they pay for the car wash. A car wash ain't worth $10 bucks from two kids.
Just assume that they are just two people acting as one person. That's what a team is.
I'd probably go for $32.50 working S/Sun Carwash for 5 hours ($25) + $7.50 on Tuesday for lawn mowing the first week
then $5/hour for 5 hours sat/sunday carwash + $6 1 hour a week MWF dog walking for $31 the next week. Keep alternating.
Don't be mean to your teacher.
