Question

Allie is baking chocolate chip cookies for a party at school. She leaves 10 at home for her family and brings the remaining 30 cookies to school to share with her classmates. Which equation can you use to find the total number of cookies (n) that Allie bakes?

Choices:

◦n + 10 = 30
◦n - 10 = 30
◦10n = 30
◦n/10 = 30

Answer 1

The second one n - 10 =30

Explanation:

n - 10 = 30 so she left 10 at home and brings 30 to school so you add 10 to both side of the equation and the one side just has N because the ten's cancels out and you add 10 to 30 which gives you 40 so the final answer is n = 40
