Tyrese’s sister is 41 inches tall. A ride at the amusement park states that riders must be at least 52 inches tall to ride. Which statements describe how much taller Tyrese’s sister must be to ride?

Let h be the required additional height.
The phrase at least means an inequality, using the >= sign, so we have:
h + 41 >= 52

If we want another way to express this, we type this inequality into our math engine and we get:
h >= 11
