Aconstruction worker is blacktopping a driveway. he blacktops 35 1/2 square. xyd2/hr yards in 5/6 hour. how many square yards can he blacktop per hour.

  42 3/5 yd²/h

Step-by-step explanation:

Divide the area by the time to find the unit rate:

  (35 1/2 yd²)/(5/6 h) = (71/2)(6/5) yd²/h

  = 213/5 yd²/h = 42.6 yd²/h

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
