In July 2009, unemployment in Michigan reached 15%. The number of workers was 4,900,000. Approximately how many were unemployed?
  1. 735,000
  2. 745,000
  3. 710,000
  4. 718,000
  5. 751,000
Explanation
Answer: A - 15% of 4.9 million people is 735,000 unemployed.

Key Takeaway: To find 15% of a 2-digit number, follow these steps:

First, multiply the number by 3 (49 x 3 = 147).

Then, divide that answer by 2 (147/2 = 73.5).

Move the decimal point. Rather than counting, use your intuition in this case. 15% should move the decimal 1 from the original millions number. (73.5 becomes 735,000).

The amount of the discount in this problem is $13.50, so the sale price is $76.50.

Key Takeaway: This works for multiplying by 1.5, 15, 150 and so on down the line so long as you keep your decimals right.
