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
