A cell phone plan costs $30.80 per month for 500 minutes of talk time. It costs an additional $0.08 per minute for each minute over 500 minutes. To get e-mail access, it costs 20% of
the price for 500 minutes of talk time. Your bill, which includes e-mail, is the same each month for 5
months. The total cost for all 5 months is $208.80. Write and solve an equation to find the number of
minutes of talk time you use each month.
Let m represent the number of minutes over 500 minutes each month. Which equation represents
the given situation?

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

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
