Question

Each year, the students in seventh grade go to an environmental camp. This year, the total cost is $1,580 for 79 students. Which equation represents the cost, y, of attending the camp for x number of students?

Select the correct answer.
y = 20x
y = 79x
y = 79x + 1580
y = 1580x + 79

Answer 1

y=20x

Explanation:

You have to find the cost by dividing the amount of money by the amount of students, to see house much each student paid. You are finding the unit price. Which is 20 because...

1.580/79=20

In conclusion,

Each student paid $20

Answer 2

y=79x+1580, this is the correct answer
