52.09

Step-by-step explanation:

Follow the acronym PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction) for order of operations problems.

1. Solve what is in parentheses. (9 - 7) = 2

48 ÷ 23 + 25 (9 - 7) = 48 ÷ 23 + 25 × 2

2. Divide. 48 ÷ 23 = 2.09

2.09 + 25 × 2

3. Multiply. 25 × 2 = 50

2.09 + 50

4. Add. 2.09 + 50 = 52.0

I know that 52.09 wasn't one of the options listed, but it is the exact answer. If you must choose one of those options, choose 50, since it is the closest.

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
