Answer:

Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644

Step-by-step explanation:

The cost equation is given as:

C=0.04x^2-5x+800

This is a quadratic equation in general form, which is:

y=ax^2+bx+c

Matching, we can say:

a = 0.04

b = -5

c = 800

The minimum occurs at  x=-\frac{b}{2a}

and the minimum value would be to place that "x" value into the equation.

First, we find the minimum using values of a and b:

x=-\frac{b}{2a}=-\frac{-5}{2(0.04)}=\frac{5}{0.08}=62.5

Plugging this into original, we get:

C=0.04x^2-5x+800\\C=0.04(62.5)^2-5(62.5)+800\\C=643.75

Rounding off to nearest whole number, we can say:

Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644

If the flotation costs are 2 percent of gross proceeds, and gross proceeds are $250,000, what is the dollar amount of flotation
alina1380 [7]

The dollar amount of the flotation costs by percent of gross proceeds is $5,000

We need to know about the percent theory first, percent is per 100. So when A is 1% of B it means that

A = 1/100 x B

From the question, we know that

The gross proceeds is given by = $250,000 and

the flotation cost is given by = 2% of gross proceeds.

We can write the flotation cost as

Flotation cost = 2/100 x $250,000

Flotation cost = 2/100 x $250,000

Flotation cost = $5,000

Hence, the dollar amount of the flotation costs is $5,000
