Finding actual cost of roast beef with 65% edible portion

[jacy]

An 8 lbs. roast beef cost $2.79/lb. The edible portion is 65%. What is the actual price of the roast.?

This is what i did

1lb cost $2.79, so 8lbs cost $22.32. Am i correct, this will be the actual price right. What do i need to do with 65%. Please help.

find the cost that you paid for the roast beef, and find how much of that 8lb roast beef was edible.

well, the amount of edible roast beef is 0.65 * 8 lb

so then you would take the price you paid and divide it by the amount that's edible to find the cost per pound. your answer isn't exactly correct
