Answer:
If the television is on sale for 15%, that means that the selling price before tax will be 100 - 15 = 5% of the original price.
1250 * 0.85 = $1062.5 ... this is your selling price BEFORE tax
Now, calculate your tax.
You would pay (1062.5) + (1062.5 * 0.065)
= 1062.5 + 69.06 (your tax)
= 1131.56 dollars
Step-by-step explanation:
Answer:
"34,814" is the correct solution.
Step-by-step explanation:
The given values are:
Intercept coefficient,

Production coefficient,
Units sold,
x = 3,500
Now,
The total cost will be:
⇒ 
On substituting the estimated values, we get
⇒ 
⇒ 
⇒ 
As the fellow above said, the particle does make a U-turn at the vertex, and we can find that out by getting the derivative of s(t) and zeroing it out to get the point of the horizontal tangent.
Bearing in mind that ds/dt is really v(t) or the velocity equation, so when we zero out the ds/dt, is the same as saying the velocity went to 0, since it got zeroed out, and then the particle goes over the vertex and changes direction.

the negative acceleration value, simply means a decreasing rate of change, so, it means the particle is slowing down and possibly coming to a stop before changing direction again.
