16× .75 = 12

now add...

16 + 12 = 28$ per pound...

to make a 75% profit on the markets investment....I think I'll have a salad instead at that price...

tigry1 [53]

<h3>Answer :</h3>

<u>Given</u> :

9(m + 5) - 3(m - 2) = 8m + 31

We have to find value of m $.$

➠ 9(m + 5) - 3(m - 2) = 8m + 31

➠ 9m + 45 - 3m + 6 = 8m + 31

➠ 9m - 3m + 45 + 6 = 8m + 31

➠ 6m + 51 = 8m + 31

➠ 51 - 31 = 8m - 6m

➠ 20 = 2m

➠ m = 20/2

➠<u> m = 10</u>
