Since the day started with 90F then every hour it dropped 11F. So if it dropped 11F every hour for four hours it is 46F

Answer: 134°F

Step-by-step explanation:

Given : A scientist is measuring the temperature change and a chemical compound the temperature dropped 11° Fahrenheit per hour from the original temperature .

Let x be the original temperature.

Then , the compound temperature after t hours is given by :_

$y=x-11t$

At t= 4 hours and x= 90°F, we have

$90=x-11(4)\\\\\Rightarrow\ x-44=90\\\\\Rightarrow\ x=90+44=134$

Hence , the compounds original temperature = 134°F
