Answer 1

Answer:

160 members.

Step-by-step explanation:

Please consider the complete question.

Students at Westbrook Middle School hold green team meetings to plan ways to help  protect the environment. This week there are 144 members at the meeting, which is 90%  of the total group.  What is the total number of green team members?

Let x represent total number of green team members.

90% of total number of green team members would be $\frac{90}{100}x=0.90x$.

Now we will equate 90% of total number of green team members with 144 and solve for x as:

$0.90x=144$

$\frac{0.90x}{0.90}=\frac{144}{0.90}$

$x=160$

Therefore, the total number of green team members is 160.
