Solve the Problem $\mathrm { H }$ (In Meters) After $\mathrm { x }$

Solve the problem.
-If a rock falls from a height of 80 meters on Earth, the height $\mathrm { H }$ (in meters) after $\mathrm { x }$ seconds is approximately $\mathrm { H } ( \mathrm { x } ) = 80 - 4.9 \mathrm { x } ^ { 2 }$
What is the height of the rock when $x = 1.5$ seconds? Round to the nearest hundredth, if necessary.

A) $72.65 \mathrm {~m}$
B) $68.98 \mathrm {~m}$
C) $91.03 \mathrm {~m}$
D) $69.2 \mathrm {~m}$
