William can eat 3 slices of pizza in 5 minutes. If he continues to eat at the same rate, how long will it take him to eat the whole pizza, which has 12 slices of pizza? How many slices can he eat in half of an hour?

William can eat 18 slices of pizza in half of an hour.

William can eat a whole box of pizza in 20 minutes.

Step-by-step explanation:

30 minutes in half of an hour, 30/5 is 6.

3 slices in 5 mins

3 times 6 is 18.

3 slices --->   12 slices

              x4

5 mins--->   20 mins

           x4

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
