Answer 1
She should put 7 students in each group. And there will be 4 groups.
Answer 2
She should put 4 students in each group and there will be 7 groups.
Explanation: 7*4 =28
Let's compute the total loan cost:

227.50 per month * 60 months = $13,650.00 TOTAL LOAN COST
I think the loan payment formula cannot be solved for rate and must be solved through trial and error.
Here is an online loan calculator:
It says the answer is 15.299 which would be
15.3% rounded

Given
There are four defenders on a soccer team
if this represents 20 percent of the players on the team
Find out the total number of players on the team.
To proof
As given in question
four defenders on a soccer team
this represents 20 percent of the players on the team
let the total number of players = x
First convert 20% in the decimal form
Than the equation becomes
0.20x =4
now solving the above equation
we get
x = 20
thus the total number of players on the team are 20.
Hence proved
-40-10x (I think, sry if it’s wrong)
X-intercept appears at when y = 0
So when cos(0.5x) = 0 -> 0.5x = pi/2 + n*pi, where n is any random integers
So x = pi + 2npi, so the angle can be pi, 3pi, 5pi, so on
