Question

I can sell 25 cookies for $42.50. Write an equation relating the total cost, c, to the number of cookies, n.

Answer 1

Answer:

25n = 42.50c

Explanation:

25 cookie sells for $42.50. Therefore, you need to add the variable n for the number of cookies on one side. Thus, $42.50 is worth 25 cookies, so you would add c for the cost on the other side, and you get 25n = 42.50c.
