The coaches and umpires in eagle rock little league are all adults. there are four coaches for each team, plus a total of fifteen umpires.

part a

write an expression to represent the total number of adults in the little league, where t is the number of teams.

part b

if there are nine teams in the league, how many adults are part of the little league? show your work.

The expression that represents the total number of adults: 4t + 1551 adults are part of the Little League

Explanation:

Part A.

1. Name the variables:

Number of teams: tNumber of adults: A

2. Write the function that models the relation between the variables:

There are four coaches for each team: 4t; it s a variable term     A total of 15 umpires: 15; it is a constant term                                                             A = 4t + 15 (total number of adults)

The expression that represents the number of adults is 4t + 15

Part B.

If there are nine teams in the league, you substitute 9 for t in the expression that represents the total number of adults in the Little League (make t = 9) to determine how mnay adults are part of the Little League:

4t + 15 = 4(9) + 15 = 36 + 15 = 51

Hence, 51 adults are part of the Little League.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.

N- 3 is the answer
