As the comments state, the velocity is the derivative of the position.
Therefore, the velocity as function of time is:
ds / dt = 24 + 6t - 3t^2.
That is a parabola whose maximum is (1,27). With that you know that the velocity will never be either 63 m/s or 81 m/s.
Also, you know that the velocity at t = 1 s is 27 m/s.
And, you can also find that the velocity at t = 3 is 15 m/s.
I am confident on that this analysis solves your question. Else, insert a comment.
Hi!
<em>Step:</em>
<h3>We need to divide $74.50 by 10.</h3><h3>So we get $7.450 </h3><h3>but we remove the 0 :)</h3><h3 /><h3>Knowing that x is the number of boxed lunches and the company would have to pay $7.45.</h3><h3 /><h3>we can just do <em>7.45x = y</em> where y is the total cost for the lunches. </h3><h3 /><h3 />
<em>So the answer is:</em>
<h3>$7.45</h3><h3 />
:D

To set the equation,we can first find how much price would be raised within a year:
=500×(1+7%)
=500×1.07
As the years go by the increase would accumulate,and the equation would be:
Hope it helps!
75.00-37.20=37.80-1.80=36.00
so she spent 36.00 with sales tax . then 36.00*2=72.00+10.00=82.00
the jeans original price was 82.00
