Megan has 25 phone numbers stored in her cell phone. abby has some phone numbers stored in her cell phone. together they have a total of 61 phone numbers stored. if n = the number of phone numbers abby has stored in her cell phone, write a mathematical sentence to express the information above.

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
