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?
