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?

a) 1.5 teaspoons
b) 3 teaspoons
c) 4.5 teaspoons
d) 6 teaspoons

Answer 1

Jasmine will use 1.5 teaspoons of vanilla to make enough cookies for her class of 36 students, as she will need to make 3 batches of cookies, with each batch requiring 1/2 teaspoon of vanilla.

Step-by-step explanation:

Jasmine is making cookies for her class and needs to determine the total amount of teaspoons of vanilla she will use. The recipe calls for ½ of a teaspoon of vanilla per batch, and each batch makes 12 cookies. With 36 students in her class, she needs to make sure each student gets at least one cookie.

To find out how many batches she needs, we divide the total number of students by the number of cookies per batch:

36 students ÷ 12 cookies/batch = 3 batches

Next, to find out how many teaspoons of vanilla are needed, we multiply the number of batches by the teaspoons of vanilla per batch:

3 batches × ½ teaspoon/batch = 1½ teaspoons of vanilla

Therefore, Jasmine will use 1½ teaspoons of vanilla for the cookies, which corresponds to option (a).
