Six ice cream cones cost $16.50. At this rate, how much do 2 ice cream cones cost?

$5.50

Step-by-step explanation:

One icecream cone costs $2.75, so two would cost $5.50.

$5.5

Step-by-step explanation:

--Use division

16.50 ÷ 6 = 2.75

--Then multiplication

2.75 x 2 = 5.5

It costs $5.5 to buy 2 ice cream cones.

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
