Answer provided by our tutors
let
d = the hours of dog-walking
c = the hours of car washing
Mitchell can work at most 20 hours next week
c + d <= 20
Mitchell needs to earn at least $92 to cover his weekly expenses.
Mitchell's dog-walking job pays $7.50 per hour and his job as a car wash attendant pays $6 per hour.
7.5d + 6c >= 92
the system of liner inequalities is
c + d <= 20
7.5d + 6c >= 92
