Question

Express each relationship as an equation. Explain what information each letter and number represents. The total money collected if the cost to go on the trip is $20 for each student. *

Answer 1

y = 20x

where x is the number of students and y is the total money collected.

Explanation:

Let's call x the number of students that go on the trip.

We will call y the total money that was collected.

If one student went on the trip, we would have 20(1) = 20 dollars collected

If two students went on the trip, we would have 20(2) = 40 dollars collected.

If we follow this pattern, if x students went on the trip, we would have 20(x) dollars collected.

As we said before, the total amount collected is y, therefore our equation would be:

y = 20x

where x is the number of students and y is the total money collected.
