Question

Your class collects cans for a local food bank. On Monday, 7 students collect 63 cans. Using the constant of proportionality, find the number of students who collect 90 cans on Tuesday?

Answer 1

10.

To solve this, you must find the number of cans collected by each step.

7x=63
x=63÷7
×=9
Then, you divide the total number of cans collected on Tuesday by 9.

So 90÷9=10.
