A shop sells one pound bags of peanuts for $2 and three pound bags of peanuts for $5. If 9 bags are purchased for a total of $36, how many three pound bags were purchased?

Answer:7

Step-by-step explanation:

5x7=35

Six

Step-by-step explanation:

What do we know?

1 lb pack = $2

3 lbs pack = $5

9 packs are purchased for $36

Solve

The biggest amount of 3-pound bags can be 7. That cannot be because that would be $35, and there are no 1-pound bags.

Go down to 6. 6 bags of 3 pounds would cost $30. You can also get 3 2-pound bags to get to 36. Cost is reached. 6+3 = 9. Number of bags reached.

six 3-pound bags
