It helps align the problem right. There is nothing to multiply there, so you have put a 0 or you'll get confused on what to do next.

iVinArrow [24]

Answer:

The sales of volume V, of a particular product with a net income of $5000 given a sales price of $40, a variable cost of $15?and $1000 in fixed cost is 240

Step-by-step explanation:

Given:  

Net income= $5000

sales price= $40

variable cost =$15 and $1000

To Find:

sales of volume V=?

Solution:

We Know that  

\text {Income}=40 * x

Where x=  number of units sold

Similarily,  

\text { Net Income }=40 \mathrm{x}-\text { VARIABLE } \cos \mathrm{T} * \mathrm{x}-1000

Substituting the known values,

\text { Net Income }=40 \mathrm{x}-\text{VARIABLE COST} * \mathrm{x}-1000

5000=40 \mathrm{x}-15 * \mathrm{x}-1000

Sloving the equation,

5000=40 \mathrm{x}-15 \mathrm{x}-1000

5000=25 \mathrm{x}-1000

5000+1000=25 \mathrm{x}

6000=25 \mathrm{x}

x=\frac{6000}{25}

x=240
