Question

Cindy is a waitress and makes $36 per night. Since this is a particularly low amount

of money, she depends on tips for her income. She earns, on average, $18 per table
in tips. How many tables should she wait on in one night if she wants to make a total
of $180?

Answer 1

8 tables

Explanation:

since she makes on average $18 per table and wants to make $180 we can just multiply $18 by 10 tables however we have to take into account the $36 she makes per night. 36 is just 18 multiplied by 2 meaning we can subtract a total of 2 tables away from the total of 10 tables to get 8 tables
