Mrs. Rodriguez wants to pay her restaurant bill which is $24.00. A 6% tax is added by the waitress. If Mrs. Rodriguez wants to leave a 20% tip on the total including the tax, how much should she pay?

$30.53

Step-by-step explanation:

First, find the tax.  To do this, first convert the percentages to decimals.

6% = 0.06

20% = 0.2

Now, multiply the bill by the decimal to find the tax.

24 × 0.06 = 1.44

Add this to the bill to find the total.

24 + 1.44 = 25.44

Now that you have the total, multiply the total by the decimal to find the tip.

25.44 × 0.2 = 5.088 = 5.09

Add this tip to the total to find how much Mrs. Rodriguez should pay.

25.44 + 5.09 = 30.53

The total is $30.53.

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.
