A student worked out at a gym continuously for 50 minutes. The graph shows the remaining percentage of the workout as a linear function of x, the time in minutes.

Which answer choice best describes the domain and range of the function for this situation?

• Domain: All real numbers greater than or equal to 0 and less than or equal to 100

  Range: All real numbers greater than 0 and less than or equal to 50.

• Domain: {-2}

  Range: {100}

• Domain: All real numbers greater than or equal to 0 and less than or equal to 50.

  Range: All real numbers greater than 0 and less than or equal to 100.

• Domain: {100}

  Range: {-2}

The school office aides are in charge of packaging up old textbooks from the book room to mail to the used bookstore. This year, the school received $600 in total for selling old math textbooks for $12 each and old paperback novels for $3 each. The school sold 71 math textbooks and paperback novels in all.

Which system of equations could be used to calculate the number of old math textbooks, m, and the number of old paperback novels, p, the school sold this year?

• 12m+3p=600

  m+p=600

• 12m+m=600

  3p-12=71

• m=12-3p

  m+p=600

• 12m+3p=600

  m+p=71
