Question

Lucia already knew 1 appetizer recipes before starting culinary school, and she will learn 3 new appetizer recipes during each week of school. After how many weeks of culinary school will Lucia know a total of 40 appetizer recipes?

Answer 1

w e can writhe a equation

`y=3x+1`

where y is the total of recipes and x the weeks

y=40 according to the text

so, we can replace y and solve x to know the weeks

`\begin{gathered} 40=3x+1 \\ 40-1=3x \\ x=(39)/(3) \\ x=13 \end{gathered}`

so she will know 40 appetizer recipes on 13 weeks
