Umesh's teacher is giving a 50-point quiz with 15 questions on it. Some of the questions are multiple-choice, and some of them are short answer questions. The multiple-choice problems are worth 3 points each, and the short-answer questions are worth 4 points each. How many questions are multiple-choice?

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
