Problema Solution
Suppose you have a job in an ice cream shop that pays $6 an hour. You also have a baby sitting job that pays $4 per hour. You want to earn AT LEAST $60 per week but would like to work no more than 12 hours a week.
1. Write a system of linear inequalites that describes this situation.
Answer provided by our tutors
Let x= number of hours worked in the ice-cream shop
Let y= number of hours worked in baby sitting
6x + 4y >= 60
6x + 4y -4y >= 60 -4y
x >= 10- (2y/3)
when y=3, x=8 and wen y=0 , x=10
x + y <= 12
x<=12-y
when y=12, x=0 and wen y=0 x=12
Both will be solid lines
solutions can be (8,3) (10,2) etc
