Question

Chapter 7.1, Problem 57E

To determine

To calculate : A small software development company invests $16000 to produce a software package that will sell for $55.95. Each unit costs $9.45 to produce.

a. How many nits must the company sell to break even?

Expert Solution

Answer to Problem 57E

a. 344 units

Explanation of Solution

Given information :

Total investment amount is $16,000

Sell the package $55.95

Each unit cost is $9.45

Calculation :

Suppose x represents the number of units sold.

Let’s write the equation using the given information.

Cost of x units = 9. 45x

9.45x+16000=55.95x55.95x−9.45x=1600046.5x=16000x=1600046.5x=344.086x≈344units

The company must sell 344 units to break even.

To determine

To calculate : A small software development company invests $16000 to produce a software package that will sell for $55.95. Each unit costs $9.45 to produce.

b. How many units must the company sell to make a profit of $100000.

Expert Solution

Answer to Problem 57E

b. 2495 units

Explanation of Solution

Given information :

Total investment amount is $16,000

Sell the package $55.95

Each unit cost is $9.45

Given profit is $100,000

Calculation :

We will write the equation

55.95x−(9.45x+16000)=10000046.5x=100000+1600046.5x=116000x=11600046.5x=2494.62x≈2495units

There are 2495 units must be sold to earn profit $100000.
