Answer: <em>x</em>
Step-by-step explanation:
For this equation, the variable <em>y</em> is dependent on the value of<em> x</em>. The value of <em>y</em> changes depending on the value of<em> x</em>. This means that <em>x</em> is the independent variable for this equation.
18 x 40 = 720 per week.....720 x 4 = 2880 per month earnings
net pay = 0.72(2880) = 2073.60 <=== cash inflow.
how much he spends per month is his cash outflow.
Let x equal the number of months
Total cost=$30 + $50x
X=5 months
So total cost= 30+50(5)=$280
4s + 12 or 4(s + 3) would be equivalent to the expression!
