After seven hours, that is, at 10 p.m the temperature will be -2 Fahrenheit
From this problem we know:
Statement 1. At 3 P.M the temperature is 12 Fahrenheit
So this is the starting point. So:
[tex]Starting \ point =12[/tex]
Statement 2. Then began dropping two Fahrenheit every hour.
Since the temperature began dropping two Fahrenheit every hour, then this is a constant rate of change. In other words, our function will be a linear function with negative slope -2 and y-intercept (starting point) 12. So:
[tex]T=12-2t \\ \\ \\ T:Temperature \\ \\ t:time[/tex]
Our goal is to find the temperature after seven hours, so:
[tex]For \ t=7 \\ \\ \\ T=12-2(7) \\ \\ T=-2^{\circ} \ Fahrenheit[/tex]
In conclusion:
After seven hours, that is, at 10 p.m the temperature will be -2 Fahrenheit
