Soft Drinks Shop Orange: Two 24-packs for $15; one 24-pack for $9 Root Beer: One 24-pack for $14 Cream Soda: One 12-pack for $5 A consumer needs to purchase at least 60 soft drinks for a picnic. Which of the following combinations is the most cost-effective?

A. 2 pack of Orange and 2 packs of Cream Soda

B. 3 packs of Root Beer

C. 1 pack of orange, 2 packs of Root Beer and 1 pack of Cream Soda

D. 4 packs of cream Soda

Answer Explanation:

Choice A: 2 packs of Orange and 2 packs of Cream Soda

  • Total drinks: 48 + 24 = 72 drinks
  • Total cost: (2 * $15) + (2 * $5) = $30 + $10 = $40
  • This choice not only meets the requirement of at least 60 drinks but also offers the best value in terms of cost per drink, making it the most cost-effective option.

Choice B: 3 packs of Root Beer

  • Total drinks: 3 * 24 = 72 drinks
  • Total cost: 3 * $14 = $42
  • While this choice meets the requirement of at least 60 drinks, it's not the most cost-effective, as it costs $42 for 72 drinks.

Choice C: 1 pack of Orange, 2 packs of Root Beer, and 1 pack of Cream Soda

  • Total drinks: 24 + 48 + 12 = 84 drinks
  • Total cost: $9 + (2 * $14) + $5 = $9 + $28 + $5 = $42
  • This choice provides more than 60 drinks, but it's not the most cost-effective due to its higher cost of $42, same as choice B.

Choice D: 4 packs of Cream Soda

  • Total drinks: 4 * 12 = 48 drinks
  • Total cost: 4 * $5 = $20
  • While this choice is the most cost effective, it falls short of providing the desired number of drinks.

Therefore, the Correct Answer is A.

  • Q #1: Which of the following is the total number of whole boxes that measure 2.5 ft * 2.5 ft * 2.5 ft that can be stored in a room that measures 12 ft * 12 ft * 12 ft, if the size of the boxes cannot be altered?

    A. 111

    B. 105

    C. 150

    D. 120

    Answer Explanation

    The number of boxes to fit the room is found as volume of the room divided by the volume of the box.

    Number of boxes:

    \(\frac{volume\ of\ the\ room}{volume\ of\ the\ box} = \frac{12ft\ *\\ 12ft\ *\ 12ft}{2.5ft\ *\ 2.5t\ *\ 2.5ft}\ =\ 110.592\)

    The approximate number of boxes that can be stored in the room is approximately 111 square feet.

  • Q #2: A child has a bottle full of pennies, nickels, dimes, and quarters. There are four as many quarters as pennies, two times as many as nickels as pennies, and seven times as many dimes as nickels. How many more dimes does the child have than nickels?

    A. 7 times as many

    B. 5 times as many

    C. 2 times as many

    D. 10 times as many

    Answer Explanation

    This problem asks us to compare the number of dimes to nickels.

    If we let p be number of pennies in the bottle. Then,

    Number of quarters in the bottle = 4p

    Number of nickels in the bottle = 2p

    Number of dimes in the bottle =7(2p)=14p

    To find the number of dimes the child has than nickels, we use the ratio:

    \(\frac{Dimes}{nickels} =\frac {14p}{2p}\ =\ 7\)

    Thus, there are 7 times as many dimes as nickels in the box.

  • Q #3: The American with Disabilities Act (ADA) requires that the slope of a wheelchair ramp be no greater than 1:12. Which of the following is the minimum length of a ramp needed to provide access to a door that is 1.5 feet above the sidewalk?

    A. 22 feet

    B. 19.5 feet

    C. 32.5 feet

    D. 18 feet

    Answer Explanation

    The slope represents the ratio of rise to run. Let p be the minimum length of the ramp, we can set a ratio equation as follows. Then,

    The minimum length of the ramp needed is 18 feet to access to a door that is 1.5 feet above the sidewalk.
