Answer:
28 students
Step-by-step explanation:
30% is equal to .3
40 x .3 equals 12
This means the class has lost 12 students.
40 - 12 is 28.
Another way:
Because the class has lost 30% of it's students, you know that the class is 70% of it's original capacity.
70% is equal to .7
40 x .7 is 28
A bag of chip = 0.85, let a bag of chip be x
a bag of gatorade is 1.50, let gatorade be y
23.70 is the amount Kennedy spent in all
0.85x + 1.50y = 23.70
step 1: shows the wrong step already, because you shouldn't take out a -0.85, and y is not 0.85 either, but 1.50, so y should still have 1.76 left
so your answer should be step 1.
hope this helps
