Mia spent 30 minutes answering the math questions on the exam. This was 5 of the total amount of time allotted for this
section of the exam. To determine the total amount of time allotted for this section of the exam, Mia set up and solved the
equation as shown below.
x = 18
Which best describes the error that Mia made?

so when she spent 30 minutes on the math exam so it went over 5 of the total amount of time allotted so to determine the total amount of time allotted for the section she set it up and solved it well x is not 18 so she messed up on her answer and she went over 5 times the time i think?

Step-by-step explanation:

(b) Mia should have multiplied both sides of the equation by Five-thirds.

step-by-step explanation:

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
