A large bakery uses a recipe for snickerdoodle cookies that needs 5 gallons of milk for 25 tablespoons of vanilla extract.

Question

The recipe uses 5 gallons of milk for every 25 tablespoons of vanilla extract. Record that ratio in the table.

Nice!
Find the unit rate. How many tablespoons of vanilla extract do you need for 1 gallon of milk?

Great job!
Use the unit rate to fill in the tablespoons of vanilla extract you need for 2 gallons and 9 gallons of milk.

Answer 1

To find the number of tablespoons of vanilla extract needed for 2 gallons and 9 gallons of milk using the unit rate (which is 5 tablespoons of vanilla extract per 1 gallon of milk), you can simply multiply the number of gallons of milk by the unit rate.

We already have:

• Milk (gallons): 5 | Vanilla extract (tablespoons): 25
• Milk (gallons): 1 | Vanilla extract (tablespoons): 5

Now we can calculate for 2 gallons:

For 2 gallons:

• Vanilla extract = 2 gallons × 5 tablespoons/gallon = 10 tablespoons

Now for 9 gallons:

For 9 gallons:

• Vanilla extract = 9 gallons × 5 tablespoons/gallon = 45 tablespoons

So, the completed table would look like this:

| Milk (gallons) | Vanilla extract (tablespoons) | |----------------|-------------------------------| | 5 | 25 | | 1 | 5 | | 2 | 10 | | 9 | 45 |
