At 7 AM it is 20° F and the temperature is dropping at a rate of 4° F per hour. What will the temperature be at 11 AM?

4 degrees

Step-by-step explanation:

7am to 11am is 4 hours.

So now multiply 4 hours*4* F = 16

So the temperature decreased 16 degrees.

20-16=4

It was 4 degrees at 11 am.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
