Kim had $83.45 to spend on buying Halloween supplies for her party. At the first store, she spent 2/10 of her money on a special costume. How much money did she spend?
This is really straightforward.....Just multiply 2/10 times the amount of money she originally had....
2/10 x 83.45 = ??? DO you know how to do that? Eventually, you'll be able to do this in your head, but using a calculator to find the answer is easy....try it!
