The cost of performance tickets and beverages for a family of four can be modeled using the equation 4x + 12 = 48, where x represents the cost of a ticket. how much is one ticket? $3.00 $4.00 $9.00 $15.00

For this case we have that the cost of a ticket is given by the variable "x". We have the following equation:

By clearing "x" we have:

We subtract 12 on both sides of the equation:

Dividing between 4 on both sides of the equation:

Then, a ticket costs $ 9.00

Option C

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.
