Jason is a used-car salesman who sells domestic and foreign cars. he earns $7,000 for each domestic car sold and loses $3,500 for each foreign car sold. due to certain business commitments, jason has to sell at least 10 foreign cars each month. he needs to make at least $17,000 each month to cover his expenses. which graph shows the number of cars he has to sell each month to at least cover his expenses?

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.

the answer is 11.2 (i know i’m late)

i agree because i see the other persons thinking is clear
