Question

Ella already knew 5 appetizer recipes before starting culinary school, and she will learn 2 new

appetizer recipes during each week of school. Write an equation that shows the relationship

between the number of weeks w and the number of appetizer recipes a.

Write your answer as an equation with a first, followed by an equals sign.

Answer 1

A = 2w+5

example: on week three, she would have the recipes from the other weeks that you have to account for as well as the extra five

2(3)+5=11 so A would equal 11 by week three.

Use multiplication because it is essentially repeated addition.

2(from week 1) + 2(from week 2) + 2(from week 3) + 5(prior to school) =11
