Jerry works no more than 20 hours a week during the school year. He is paid $10 an hour for tutoring geometry students and $7 an hour for delivering pizzas for Pizza King. He wants to spend at least 3 hours, but no more than 8 hours, a week tutoring. Find Jerry’s maximum weekly earnings.
1 answer:
Works no more than 20 hours/week 3-8 hours tutoring Subtract 3-8 from the 20 to give you hours for pizza delivery So anywhere between 12-17 hours for pizza delivery To find his maximum weekly hours (keeping in no more than 20 hours) 3 hours tutoring 17 hours pizza 3 x $7 = $. $21 17 x $10 = $170 ----------------------- $191 If he did 8 hours of tutoring 12 hours of pizza 8 x &7 = $56 12 x $10 = $120 ------------------------ $176 So he'd be better off working more hours delivering pizza & less doing tutoring
