(Set up and solve the system, then answer the associated question) An indoor soccer team has a blue and a red division. There is one more team in the red division than the blue division. The average number of goals scored per week in the blue division is 4.2 and the average number of goals scored per week in the red division is 4.5. The average number of goals scored per week in both leagues combined is 48 total goals. How many teams are in each division?

(I think I’m mostly stuck on how I would set this problem up, but I would appreciate any help at all!! Thank you ^^)

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
