Answer:
4/3
Step-by-step explanation:
I used a site and my calculator
There would be 5/2 cup servings
2x-y=-1 (1)
3x-2y=1 (2)
(1) * 2--> 4x-2y=-2 (3)
(3) - (2)
x= -3
sub x= -3 into (1)
2(-3)-y=-1
-6-y=-1
-y=5
y= -5
18 students are 100%-37,5%-40%=22,5%
18 students - 22,5%
x students - 100%
22,5x=18×100
x=80
Answer: 80 students
