Question

Jasmine is making cookies for everyone in her class and she wants to make sure everyone gets at least one cookie. The recipe calls for ½ of a teaspoon of vanilla for every batch and each batch makes 12 cookies. If her class has a total of 36 students, how many teaspoons of vanilla will Jasmine use?

Answer 1

1.5 or 3/2 teaspoons

Explanation:

If her class has 36 students, and there are 12 cookies in every batch, then she needs 3 batches to give everyone in her class 1 cookie each. It takes 1/2 teaspoon for every recipe, so she needs 3 of those. 3 × 1/2 = 1.5 (or 3/2)
