At work john is paid 40 day and 5 for every otem he sells. if he made 445 how many items did he sell

Can you explain more in detail? Does he get $40 dollars per day, and does he work 5 days a week? Or does he work 4 days a week? I need to know how many days per week he works, and I will help you solve this. :)

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
