Question

. The total cost (t) is proportional to the number (n) of items purchased at a constant price of $3.

What is the equation?

Answer 1

t = 3n

Explanation:

n and t are proportional so you know they will be on the opposite ends of the equal sign. Then you know that the items are purchased at the constant price of $3. That means you do the number of items times 3 to get the total cost.
