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.
