Gracie, Mary, and Nancy each have a small collection of seashells. Gracie has 5 more than 1 and 1/4 times the number of shells Mary has. Nancy has 1 more than

1 and 1/2 times the number of shells Mary has. Gracie and Nancy have the same number of shells. If x is the number of shells Mary has, identify the equation that

represents this situation and identify its solution.

• 3/2 x + 1 = 5/4 x + 5, x=16

• 3/2 x + 1 = 5/4 x - 5, x=18

• 3/2 x - 1 = 5/4 x + 5, x=24
