  • Q #2: A patient drives 19 miles one way to a medical facility for treatment. How far does the patient drive round-trip in 22 days of treatment?

    A. 1,254 miles

    B. 1,672 miles

    C. 418 miles

    D. 836 miles

    Answer Explanation

     Round trip means to and from, which is twice the distance from home to a medical facility.

    In one day, the round trip=19+19=38 miles

    So, in 22 days, the round trip=38*22=836 miles.

    The patient will cover 836 miles in 22 days.

  • Q #3: To rent tablecloth from a rental vendor, there is an initial charge of $40. There is an additional charge of $5 per circular tablecloth (c) and $3.50 per rectangular tablecloth (r). Which of the following represents the total cost (T) to rent tablecloths?

    A. 5r + 3.5c - 40 = T

    B. 5c + 3.5r + 40 = T

    C. 5c + 3.5r - 40 = T

    D. 5r + 3.5c + 40 = T

    Answer Explanation

     From the given scenario:

    Initial charge is $40

    Additional charge per circular cloth=$5c

    Additional charge per rectangular cloth=$3.50r

    Total cost = additional charge per circular rectangular cloths + Initial charge

    Total cost, T = 5c + 3.5r + 40
