next step @ivettef365

OpenStudy (mathstudent55):

The answer above is incorrect. This is how you do it. Since you want the average price per pound, that means you need to divide a price by a weight. Divide the total cost by the total weight. You are given the total cost: $8.68. You are given two weights: 0.70 lb and 0.75 lb. Add the weights together to find the total weight. Then divide the total cost by the total weight.

so its the same thing that ivettef365 told me?

OpenStudy (mathstudent55):

No. Ivette told you to divide the weight by the cost. You need to divide the cost by the weight.

OpenStudy (mathstudent55):

You didn't do either. The answer is nowhere near $16.7/lb
