We are told that 50 people need 4 cups of sugar. This can be interpretated as:

Or

Also, one bag of sugar contains 6 cups. This can also be presented as:

Or

We use the second option relating number of people and cups, and second option relating cups of sugar and bag of sugar to find for number of bags of sugar needed for 300 people.

 

Therefore, 300 people will need 4 bags of sugar.

Therefore, the Correct Answer is C.

  • Q #2: The width of a rectangle is 4 inches (in) and the area of the rectangle is 32 in2. Which of the following is the length of the rectangle?

    A. 8 in

    B. 28 in

    C. 36 in

    D. 128 in

    Answer Explanation

    We need to find the length of the rectangle from the given area and width of the rectangle. Let L be length if the rectangle. Then,

    Area of rectangle=Length*width

    Substituting area=32 in2 and w=4 inches

    32=L*4

    32=4L

    Divide both sides by 4

    32/4=4L/4

    8=L

    The length of the rectangle is 8 inches.

  • Q #3: Which of the following is the value of x in the equation below? 4x- 3- 5x=24

    A. -27

    B. -6

    C. 3

    D. 21

    Answer Explanation

    to solve for x, we order like terms together and proceed as follows:

    4x-3-5x=24

    Add 3 to both sides of the equation

    4x-3+3-5x=24+3

    4x+3-3-5x=27

    4x-5x=27

    -x=27

    Divide both sides by -1

    -x/-1=27/-1

    x= -27

    Thus, the unknown value of x is -27
