Mitchel is half as old as Damon, and Damon is 3 years older than Tiffany. If x represents Tiffany's age, what expression represents Mitchel's age?

m = (3t) / 2, or (3/2) t

Step-by-step explanation:

Represent the unknowns as follows:

d: Damon's age; t: Tiffany's age; and m: Mitchel's age.

Then: m = d/2; d = 3t. Replace "d" in the first equation by "3t" from the second equation:

m: Mitchel's age: m = (3t) / 2, or (3/2) t.

x+3/2 so also option c.
