ANSWER:  

Arlene is getting hours of sleep in a week.

SOLUTION:

Given, Arlene sleeps for seven hours and 20 minutes each night

We need find how many hours of sleep does she get in a week as a mixed number?

Now, total sleeping time for each night is 7 hours and 20 minutes

Let us convert hours in to minutes first and then in last we can convert it again to hours.

Sleeping time per one night = 7 hours + 20 minutes

= 7 x 60 minutes + 20 minutes

= 420 + 20 minutes

= 440 minutes

Now, sleeping time per one week = sleeping time per one night x 7 nights

= 440 x 7

= 3080 minutes

Now, sleeping time per week in hours =

[20 is remainder]

Hence Arlene is getting hours of sleep in a week.

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
