Currently 100 students can eat for 20 days, so we need to find the number of days 125 students can eat.
Originally:
100 students eat for 20 days
New:
125 students eat for x days. Multiply original number of students by original number of days which will give the total amount of students per day. Then divide the total amount of students per day by the new number of students to find the new number of days.
x= (100 students * 20 days)/ (100+25)
x= (100 * 20)/ 125
x= 2000/125
x= 16 days
ANSWER: 125 students can eat for 16 days.
Hope this helps! :)

I took the test and got it right.
Answer: +42x
Step-by-step explanation:
The student only multiplied each term individually.
He should have (7x+3)² = (7x+3)(7x+3)
Which is 49x²+42x+9
Therefore the error is (42x) or the failure to apply the law of multiplication of variables in a bracket.
First, simplify the parenthesis. You’ll get:
1/4(4z)+7=-z+1
Then multiply 1/4 by 4z. You’ll get:
z+7=-z+1
Love like terms to the same side. I wanted to have the variable positive on time, so I moved variables to the left and constants to the right. You’ll get:
2z=-6
Divide both sides by 2. You’ll get :
z=-3
