Chapter ISG, Problem 2.1.1.7P

a.

To determine

To write a problem based on the information

Answer to Problem 2.1.1.7P

Constraint on n is 1.65 and 4.25

Explanation of Solution

Given information:

  $4.25n-1.65n=P$

Calculation:

  $1.65n$ is the making price of the bracelet and $4.25n$ is the selling price of the bracelet.

P is the profit.

Constraint on n is 1.65 and 4.25

b.

To determine

To simplify the equation

Answer to Problem 2.1.1.7P

  $2.60n=P$

Explanation of Solution

Given information:

  $4.25n-1.65n=P$

Calculation:

The given equation is $4.25n-1.65n=P$

Solving equation,

  $(4.25-1.65)n=P$

So,

  $2.60n=P$

The coefficient of n is means the amount of profit made on per bracelet.

c.

To determine

To tell how many bracelets were sold

Answer to Problem 2.1.1.7P

47 bracelets were sold

Explanation of Solution

Given information:

Profit made= $122.20

Calculation:

Profit made=122.20

Substituting equation,

  $2.60n=122.20$

Solving the equation,

  $n=\frac{122.20}{2.60}$

So,

  $n=47$

Hence, 47 bracelets were sold.

d.

To determine

To tell the effect on constraint

Answer to Problem 2.1.1.7P

No effect on constraint

Explanation of Solution

Given:

Profit least earned=$100

If profit of 100 dollar is to be made, there will be no effect on constraint of n. It is because, the amount of profit will be same on every value on.
