At the museum, Bethany saw 4 times more still lifes than portraits. If she saw 80 paintings total, how many portraits did she see?
Define a variable ** Let s be the number of still lifes Bethany saw and p be the number of portraits. We know that s + p = 80 and s = 4p.
Write an equation ** Substituting the second equation into the first equation, we get 4p + p = 80
Combine like terms ** Combining like terms, we get 5p = 80
Divide by 5 ** Dividing both sides by 5, we get p = 16
