Answer:
it will take A 4.5 hour
Step-by-step explanation:
Say both teams are of same man power, and here we have two teams
A and B
B takes 13 hours to finish a task.
A&B takes 8.5 hours to finish same tasks
Hence it will take A 13-8.5=4.5 hours to complete the task
Using the permutation formula, it is found that the people can be chosen for the roles in 6840 ways.
The order in which the people are chosen is important, as there are different roles, hence the <em>permutation formula</em> is used.
<h3>What is the permutation formula?</h3>
The number of possible permutations of <u>x elements from a set of n elements</u> is given by:
In this problem, 3 people will be chosen from a set of 20 people, hence the number of ways is given by:

Answer:
D) Abner can spend $60 per month on school clothes and $20 per month on gym clothes and stay within his budget.
Step-by-step explanation:
In the problem it states that Abner will spend 3 times more on (s)school clothes than (g) gym clothes.
So it would appear as s ≥ 3g.
If we plug in $60 as s (school clothes) and $20 as g (gym clothes), the statement is true.
60 ≥ 3(20)
60 ≥ 60. These numbers make the linear system true.
If you have trouble with this, an easy way to find this answer is simply creating the linear system that represents the problem, (he will buy 3 times more school clothes than gym clothes) s ≥ 3g and plug in each variable from the answer choices until you find the variables that make the linear system true.
