Pls, answer 14 a b and c show your work

A: 71$

B: 56$

Step-by-step explanation:

A (3*12$)+(2*19$) -3 = 71

B(3*(12$-3$)) + (2*(19$-3$))= 56$

C If pani buys clothes and each item gets a 3$ discount then the price overall will be lower than if she only got a 3$ discount overall.

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.
