Problema Solution

maria is a waitress and earns $5.50 per hour plus an average tip of $7 for every table served. how many tables must she serve to earn more than $64 for a 4-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:

total=5.5x+7y

where 'x' is the number of hours worked and 'y' is the number of tables served.


Plugging in 64 for 'total' and 4 for 'x', we get:

64=5.5(4)+7y


Solving for 'y', we get:

y=6


Therefore, she must serve 6 tables
