Question

Tanvi is on vacation at Gull Lake. To keep in touch, she decides to send 3 postcards each day.Write an equation that shows the relationship between the number of days Tanvi has been on vacation, x, and the total number of postcards she has sent, y.

Answer 1

3x=y

Explanation:

Because we are writing this as an equation, we know there has to be an answer, or what we are looking for. In this case, it's y, the total amount of post cards sent. We find the total (y) by multiplying the number of post cards sent each day (3) times the amount of days Tanvi is on vacation (x). This will then equal y.
