Answer:
20 > 2w + 4j
Explanation:
It feels as though some of the information is missing. So, based upon the information provided above, this is the best equation I can come up with. The total amount is up to $20 (but not including $20, so it is an inequality, meaning that $20 cannot be used). 20 is greater than the sum of the number of bottles of w (water) multiplied by the $2 (cost of water) and the number of bottles of j (orange juice) multipled by the $4 (cost of the orange juice).
