### Robby's 2nd Growing post

Question 1: 1)What strategies were needed?
-I used a Ratio table, maybe some money strategies, and division and multiplication between both answers
2)How did you use these strategies?
-
For the multiplication and division between both answers part, to get 1/2 cups, I answered 12 cups by multiplying 2 2/5 (2.4) by 10 to get 24, then divide it by 2 to get 12. Then I divided 12 by 12 and then by 2 to get 1/2.
( 2.4 x 10 = 24 ÷ 2 = 12 cups 12 ÷ 12 = 1 ÷ 2 = 1/2 cups. *Then do same strategy for the ingredients and price.)
-The ratio table was basically the same information as the multiplication and division part, but with a visual aide and a little neater

3)Or How could you of used these strategies.
-The Money Strategy
-I would have used a money strategy, but it just asked you to find how much it costed, not how many pennies, nickles, and dimes you would need to give Betty to buy her snack mix. So in short, this strategy didn't really help, wouldn't get extra marks for because it didn't answered any questions, and would just be a waste of time.
4)How would you figure out the price of a 6 cup bag of Betty's Snack mix? Use a ratio table
-To get 6 cups, I would multiply the cups and price for a 2 2/4 container by 10, then divide the answer by 2, then divide it by 2 again to get 6 cups.

5)Find 3 other values (amounts of Snack Mix) that could be solved using the same ratio table. Find the \$\$ of your new container sizes.

-The 3 others are circled in green. For the price of 3 cups, I add
ed the price of a 1 cup and 2 cup container to get it.

Question 2:

I think i did a good job on this growing post. I couldn't take any photos because paint would have been much faster for me to do it with and I didn't finish the investigations in class and couldn't take a picture of it.
For 5 hours straight of working on this, I think i should get a decent mark, like 23/25 or something...
