Arestaurant has fixed costs of $147.50 per day and an average unit cost of $5.75 for each meal served. if a typical meal costs $7, how many customers must eat at the restaurant each day for the owner to break even?

The answer is 118.

Step-by-step explanation:

First we need to subtract the meal cost from average unit cost for each meal:

A restaurant profits 1.25$ for each meal. If we divide fixed cost to profit for each meal:

The restaurant have to sell 118 meals at least each day for the owner to break even

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
