Answer:

9 cups

Step-by-step explanation:

Answer:

X=18

In order for Bernie to make a profit of at least 20$ then he would need to sell 18 cups, meaning X would have to be 18.

Step-by-step explanation:

Add 20+6.50

(You add 6.50 because Bernie spends 6.50 on ingredients so you have to make more than it to make profit at all)

Divide 26.50 by 1.50

You get 17.66666....

Estimate to get 18

Check answer

18*1.50=27

27>26.50
