Question

Leon already knew 24 appetizer recipes before starting culinary school, and he will learn 2 new appetizer recipes during each week of school. After how many weeks of culinary school will Leon know a total of 100 appetizer recipes?

Answer 1

Answer: It will take him 38 weeks.

Explanation:

We will model the situation by an equation.

Leon already knew 24 appetizer recipes so it will be permenant. He will learn to more each week so we can achieve the expression . 24 + 2x where x is the number of weeks.

If we want to know the number of weeks it will take him to learn 100 appetizer recipes then we will have to set the equation equal 100.

24 + 2x = 100 Now solve for x

-24 -24

2x = 76

x = 38
