Step-by-step explanation:

Given : Price-club sells a 12-ounce package of spaghetti noodles for $3.44.

By unitary method ,

The unit price per ounce at Price-Club  = (Price of 12-ounce package of spaghetti noodles ) ÷ 12

= $3.44÷ 12 = $ 0.286666666667≈ $0.29

Hence, the unit price per ounce at Price-Club  =$0.29

Shop Mart sells a 2-pound box of spaghetti noodles for $8.35.

Since 1 pound = 16 ounces

⇒ 2 pounds = 2 x 16 ounces = 32 ounces  (By unitary method)

i.e. Shop Mart sells a 32-ounces box of spaghetti noodles for $8.35.

The unit price per ounce at Shop Mart  = (Price of 32-ounce package of spaghetti noodles ) ÷ 32

Hence, the unit price per ounce at Shop Mart is $0.26.

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
