Use the high-low method to estimate a cost function for total monthly driver's ed costs based on number of students. Y=$ x+$ Attempts: 0 of 3 used Sharon had to come up with a unique data collection and analysis project to present to the class. After much hair-pulling and teethgrinding, she came up with a cool idea. Sharon's brother mowed the neighbor's lawn every week unless it didn't rain enough for the grass to grow, in which case he'd wait a few days and then check the status again. She figured there had to be some connection between inches of rain in a week and hours of lawn mowing-or rather, money earned from mowing, since he got paid by the hour. She collected weekly data for 8 weeks using official precipitation reports from the local news station and amounts earned from mowing according to her brother. (b1) Use the high-low method to generate a cost function for this relationship. (Round answers to 2 decimal places, eg. 15.25.) Y=$ x+$
