To win a trivia game, Nevan must score 90 points. Each correct answer is worth 1 and 3/4 points, and each incorrect answer is worth −14 points.

If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?

Step-by-step explanation:

For correct questions

1 correct questions = 1 3/4 points

1 correct question = 7/4 points

Since he got 58correct questions, tgw total points he earned will be;

58 × 7/4

= 406/4

= 101.5points

For incorrect questions

1 incorrect question = -14points

22 incorrect = -14×22

22incorreft = -308points

Total points gained/lost =-308+101.5

Total points lost = -206.5

Since Nevan has a negative point of -206.5, this means that he lost.

He scored -206.5points

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
