Your total at a restaurant is $50. If you
want to tip the server
15%, what is your
total?

tip: $7.50

total: $57.50

Step-by-step explanation:

you change the 15% into a decimal by moving the the decimal point 2 spots to the left so now you have .15

next do .15 * 50 to get 7.5, which is the tip

now to find the total, add 7.5 + 50 to get 57.5

your total cost would be $57:50

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.
