Textbook Problem

Engineers at Triangle Electronics use special silver wire to manufacture fuzzy logic circuit boards. The wire comes in 840-foot rolls that cost $1,200 each. Each board requires

a. How many circuit boards can be made from each roll?

b. What is the cost of wire per circuit board?

**(a)**

To determine

**To calculate:** The number of circuit boards that can be made from each roll of wire of length

840 foot which costs $1200 each if, each circuit board requires

Explanation

**Given information:**

The length of each roll is 840 foot. Also, each board requires

**Formula used:**

Division method:

Step 1: If there are any mixed numbers or whole numbers in the expression then convert them into improper fraction and then put them in the expression.

Step 2: Identify the dividend and divisor in the given fractions. The number after

Step 3: Change the “divided by” sign,

Step 4: Simply write the multiplication of the obtained fractions.

Step 5: Find a common factor which divides at least one of the numerators and one of the denominators evenly.

Step 6: Divide the numerator and denominator by the corresponding common factor to reduce the expression.

Step 7: Repeat this process until there are no more common factors other than 1 are left.

Step 8: Now, multiply all the simplified numbers to get the lowest term.

Step 9: If the fraction obtained is an improper fraction then convert it into a whole or mixed number, otherwise if the fraction is proper fraction then stop.

**Calculation:**

The length of wire is 840 foot.

The requirement of wire of each circuit board is

Therefore, the number of circuit boards that can be made is calculated as:

Now, follow division method:

First convert the mixed number

And, the whole number as:

**(b)**

To determine

**To calculate:** The cost of wire per circuit board if the roll of 840-foot costs $1200 each and each circuit board requires
