How many 1 3/5 inch thick books can fit on a 14 1/2 inch long bookshelf

books.

Step-by-step explanation:

First, let's turn both mixed numbers into fractions:

Then, to find how many books can fit into the bookshelf, you simply divide the  space in the bookshelf by the thickness of each book:

If you want the answer as a mixed number:

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
