Admission to a zoo costs $10 for adults and $6 for children. A group of 29 people attending the zoo paid a total of $222 in admission fees.

Write a system of equations to represent the situation. Let a represent the number of adult admissions, and let c represent the number of child admissions.
Solve the system you wrote in part (a) using the substitution method. Show your work.
Interpret your solution in the context of the problem.

The number of adult admissions was 12 and the the number of child admissions was 17

Step-by-step explanation:

Let

a ----> represent the number of adult admissions

c ----> represent the number of child admissions

we know that

A group of 29 people attending the zoo paid a total of $222 in admission fees

so

----> equation A

----> equation B

Solve using the substitution method

substitute equation A in equation B

solve for c

Find the value of a

therefore

The number of adult admissions was 12 and the the number of child admissions was 17

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.
