E(t) is the elevation Maria is at at t minutes.

The expression to calculate the elevation is 1200 + 40t.

E(t) = 1200 + 40t

E(15) means the elevation Maria is at at time 15 minutes.

E(15) = 1200 + 40(15)

E(15) = 1200 + 600

E(15) = 1800

E(15) = 1800 means that Maria is at an elevation of 1800 ft after 15 minutes.
