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.
