Question 74629

1. 
Let x=number of hours per week that she may work
Then $116<=$5.80(x)<=$145  divide each term of the inequality by $5.80
20<=x<=25------------------answer

CK
$5.80*20=$116
$5.80*25=$145

2.
Let x=the income that he must have to live comfortably
Now we are told that the government will get 24% of his income or (0.24x)
If the government gets 0.24x, then Gary will have x-0.24x left for himself and this has to equal $30,000.  So our equation to solve is:

x-0.24x=$30,000
0.76x=$30,000 divide both sides by 0.76
x=$39,473.68-----------------------------------ans
