Step-by-step explanation:

it makes sense when u tink about ot

Jamil buys 6 pens.

Step-by-step explanation:

Jamil buys 4 books and each book costs £5.95. With 5.95+5.95+5.95+5.95 = £23.80. We have the total price for the books. The total cost of books and pens is £37.90 and each pen costs £2.35. If we keep adding £2.35 to our £23.80, we will get £37.90.                                                                                       If we add 23.80+2.35+2.35+2.35+2.35+2.35+2.35 = £37.90. We now have our total amount, and the prices of the amount of books and pens Jamil bought. Jamil bought 6 pens as it equals to £37.90.

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
