Basic Algebra donut question
If a donut shop sells a dozen donuts for $6.00, what would the cost of 9 donuts be? Is a fraction the right way to solve this problem? • April 7th 2012, 10:58 AM skeeter Re: Basic Algebra donut question Quote: Originally Posted by vaironxxrd If a donut shop sells a dozen donuts for$6.00, what would the cost of 9 donuts be?

yes ... $\frac{9}{12} \times 6.00$ , or figure out each donut costs 50 cents ...

Or, note that if a dozen donuts cost $6.00, 6 donuts (half of 12) cost$3.00, and 3 donuts (half of 6) cost \$1.50. And 9= 6+ 3.
