#### Storyboard Text

• Hey Sissy! I need you to babysit Ryan and Abby during lunch tomorrow!!﻿
• Hey honey!! Of course I can! Even Noah has been dying to see them!
• Hey mom, Can I invite some of my friends over for lunch tomorrow? Pleaseee!!!
• Of course!! Thanks mom you're the best!!
• Yes, even your cousins will be dropping in. Is that okay?
• Is everything okay hon? You seem very confused!
• Noah wants to host a lunch party tomorrow. But I don't know how many pasta sauce bottles I need to buy.
• You can solve that using Direct Variation.  Let the Number of people = k* The number of bottles.  Solve for k. Then substitute your new values into the equation including the value of k, then solve for y.
• HAHAHA....How many people does one bottle serve?
• Hmmmm.... It serves 2 people. But there are around 10 kids coming.
• Okay let me try that tomorrow!
• So if 2 people needed = k*1 bottle. Then k = 2/1= 2. But now I have 10 people so , 10 = 2*number of bottles needed. Therefore,  bottles = 10/2 = 5 bottles.
• Thanks mom! You're the best chef ever!
