64% make it to decimal for twice to the left

0.64 and subtract so your answer is 3.86

She is charging 7.38 per necklace. All you have to do is make the percentage a decimal (move it twice to the left so it becomes. 64) and they multiply it by how much it costs her to make (4.5). Your equation should be (4.5*.64) and that should be equal to 7.38.
