Problema Solution

Answer provided by our tutors
let
b = the time spent babysitting, b>=0
s = the time working at the grocery store, s>=0
you can work at most 24 hours next week
b + s <=24
you need to earn at least $100 dollars to cover your weekly expenses
7*b + s*6.50 >= 100
the system of inequalities that describe the situation is
b + s <=24
7*b + s*6.50 >= 100
