Leroy’s house is 14.5 feet tall. The Willis Tower in Chicago is 100 times as tall as Leroy’s house. What is the difference in height between the Willis Tower and Leroy’s house?
Enter your answer in the box.

The difference in heights is 1435.5 feet.

Step-by-step explanation:

If the Willis tower is 100x as tall as Leroy's house, its height would be 14.5 times 100, which is 14500. 14500-14.5 is 1435.5, which is the difference in heights.

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
