Explain how multiplying with 6 is like multiplying with 3

Option C.

Step-by-step explanation:

It is given that Organic milk costs $2.52 per half gallon.

1/2 gallon = $2.52

1 gallon = $2.52×2 = $5.04

Unit price = $5.04

We need to find the price of 4 gallons of organic milk.

Price of 4 gallons of organic milk = 4 × Unit price

                                                       = 4 × $5.04

                                                       = $20.16

The price of 4 gallons of organic milk is $20.16.

The price of 4 gallons of organic milk can be determined by finding the unit price and multiplying it by 4.

Hence, the correct option is C.
