A paint store mixes 3 4 pint of red paint and 2 3 pint of white paint to make a new paint color called Perfect Pink. How many pints of red paint would be needed to make 34 pints of Perfect Pink paint? A. 9 B. 16 C. 18 D. 25 1 3 E. 28 1 2 Solution First, determine how much paint the recipe for Perfect Pink will make. 3 4 pint + 2 3 pint = 9 12 pint + 8 12 pint = 17 12 pints, or 1 5 12 pints. The ratio of red paint in the recipe is the same as it will be in the 34 pints of paint. Let N be the number of pints of red paint needed. 3/4 1(5/12) = N 34 3 4 (34) = 1 5 12 (N) 102 4 = 17 12 N 102 4 ÷ 17 12 = N 18 = N Thus, 18 pints of red paint are needed, and the answer is C.

In Example 2, you can apply a property from geometry that says that when two chords intersect inside a circle, the segments formed have lengths such that the product of the segment lengths is the same for each chord. 2. Apply basic properties of numbers. In Example 4, you can use the definition of a prime number so that you do not include 1, but do include 2. 3. Eliminate as many answers as possible so that you can select from a smaller set of answer choices. In Example 3, you can eliminate some of the answers by noting that since each can of mixed nuts is at least 30% peanuts, the mixture of the two cans will be least 30% peanuts. Thus, before doing any computation, you could eliminate answers A, B, and C. Therefore, if you need to guess, you only have two answer choices left and have increased your odds of guessing correctly. 4. Substitute answers into the given question to see which one produces the ...
