2-20.

Solve the following problems. Homework Help ✎

  1. A typical small bag of colored candies has about 135 candies in it, 27 of which are blue. At this rate, how many blue candies would you expect in a pile of 1000 colored candies?

    Try constructing a proportion to solve this problem. What portion of 135 is 27? Your answer should be this same portion of 1000.

    200 candies

  2. Ten calculators cost $149.50. How much would 100 cost? 1000? 500?

    As in part (a), you can set up 3 different proportions to answer the 3 parts of this question. Or you could find the cost of a single calculator and use this to find the price of 100, 1000, and 500 calculators.
