Which type of word problem is shown?

part-whole

comparison

multiplication

division

Step 1: Find the total number of bottles bought by Caryn and Kip

Number of juice bottles bought by Caryn = 3

Number of juice bottles bought by Kip = 2

So, total bottles bought by Caryn and Kip = 3 + 2 = 5 Bottles

Step 2: Find the number of bottles bought by Kip's mother

Kip's mother buys twice as many juice bottles as bought by Caryn and Kip. Since Caryn and Kip bought 5 bottles, Kip's mother bought 10 bottles as twice of 5 is 10.

This is a comparison problem, as the problem statement compares the number of bottles of Kip's mother to that of Caryn and Kip. Although the solution also involves addition and multiplication but the main underlying concept that this problem teaches is the comparison.
