Terrance needs to score 25 points to win a game. He has already scored 18 points. The equation 18 + p = 25 can be used to find the number of points p that Terrance still needs to score. Determine whether p = 7 or p = 13 is a solution of the equation, and tell what the solution means.
Madeline has used 50 sheets of a roll of paper towels, which is \(\cfrac{5}{8}\) of the entire roll. The equation \(\cfrac{5}{8}\text{s} = 50\) can be used to find the number of sheets s in a full roll. Determine whether s = 32 or s = 80 is a solution of the equation, and tell what the solution means.
