Answer 1

Hello :)<br /><br />This is the answer (according to how I think it is)<br /><br />Put the ratio 10:14 (price of the two ingredients) and add them.<br /><br />Then you get 24<br /><br />Divide 576 with 24 and you get 24<br /><br /><br />Multiply the two ratios <br /><br />10x24= 240<br />14×24= 336 bluegrass= 240 ryegrass= 336
