Answer:

y = 3x , where x is number of notebook she buys and y is the total cost she paid.

Explanation:

Given :A store sells notebooks for $3 each and does not charge sales tax

And Adele buys x notebooks and y represents the total cost of the notebooks she buys.

We have to write an equation in terms of x and y.

Since, Adele buys x notebooks and given that the cost of each notebook is $3.

So, cost of x notebook is 3x.

And y represents the total cost of x notebooks she buys so

y = 3x

Thus, y = 3x where x is number of notebook she buys and y is the total cost she paid.
