Yesterday, jim went on a bike ride. his average speed was 10 miles per hour. today, he went days, he biked for a combined total time of 9 hours. on another ride, this time averaging 12 miles per hour. in the two let x be the number of hours he biked yesterday, write an expression for the combined total number of miles he biked in the two days

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
