Alfonso is trying to move a new sofa into his apartment. Unfortunately, he forgot to measure the size of his doors and it turns out the sofa won´t fit through! He must therefore lift the sofa from the street and bring it into the apartment through his window. The sofa has a mass of 160Kg. With a rope Alfonso can pull upwards with a force of 400N.

Calculate how much mass Alfonso can lift alone. State whether he will need to ask for help from his friends, and if so, how many friends will he need to ask?

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
