Write an equation. Then, solve and check.
-As a result of a cold front moving into the region, the temperature dropped 7.4 degrees Fahrenheit to $73.5^{\circ} \mathrm{F}$. What was the temperature before the cold front moved into the region?
A) $\mathrm{x}-7.4=73.5 ; \mathrm{x}=66.1^{\circ} \mathrm{F}$
B) $73.5-x=7.4 ; x=80.9^{\circ} \mathrm{F}$
C) $x=73.5-7.4 ; x=66.1^{\circ} \mathrm{F}$
D) $x-7.4=73.5 ; x=80.9^{\circ} \mathrm{F}$

The correct equation to represent the situation is $x - 7.4 = 73.5$, where $x$ is the temperature before the drop. Solving this equation gives $x = 80.9^{\circ}F$, which means the temperature was $80.9^{\circ}F$ before the cold front.
