At a restaurant, n cups of tea are made by adding t tea bags to hot water. If t = n + 2, how many
additional tea bags are ne
needed to make each
additional cup of tea?

1

Explanation:

This is just like a linear equation, since it is a positive number the units are increasing by 1 unit. If we were to plug this into a graph we can see that 2 is the y-intercept which means with 2 tea bags you have 0 cups and for every additional cup of tea you need another teabag, meaning the increase, or slope of the equation so the answer is 1.

Hope this helped :)
