how do i work this out

Question

Paul's grocery received 1,000 pounds of onions at 0.12 per pounds on the average 4% of the onions will spoil before selling find the selling price per pound to obtain a markup rate of 180% based on cost?

Answer 1

1000 multiply by 0.12 multiply by 180/100 = 216$ money grocery wants to make

1000 multiply by 4/100 = 40 pounds of onion will spoil, so grocery will sell: 1000 minus 40 = 960 pounds

selling price per pound is the amount of money the grocery wants to make 216$ divided by 960 pounds the grocery, which is 0.225 per pound which you can round at 0.22
