Problema Solution
Maria is a waitress and earns $5.50 per hour plus an average tip of $8 for every table served. How many tables must she serve to earn more than $129 for a 6-hour shift? Describe the situation with a linear inequality and then solve the inequality.
Answer provided by our tutors
The total amount that Maria earns on a shift can be expressed as:
5.5x+8y, where 'x' is the number of hours worked and 'y' is the number of tables served.
In our case x = 6 hours and the amount:
5.5*6+8y > 129 (since she needs to earn more than $129)
Solving for y , we get:
y>12
Therefore, she must serve more than 12 tables.
