The correct answer is y=3/2x-7 :)
Earnings=20% of sales+7.5h+40
coeficinets are 7.5 and 0.2
vraiables are h and s
constant is 40
B. if h=25 and s=30 input,
7.5*25+0.2*300+40=$287.50
C
new equation is 9h+0.2s+40
coefienct woud be 9 and 0.2
variable is h and s
constant is 4
I have a strong felling the answer is the fourth shoice according to my calculations.
The given compound inequality is
First we solve the first inequality,
Now we solve the second inequality
So we have
So the required solution is
Correct option is A .
