Write the repeating decimal as a fraction.<br> 0.928
solmaris [256]

To convert the decimal 0.928 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

0.928 = 0.928

1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 3 numbers after the decimal point, we multiply both numerator and denominator by 1000. So,

0.928

1

= (0.928 × 1000)

(1 × 1000)

= 928

1000

.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(928,1000) = 8. So,

(928÷8)

(1000÷8)

= 116

125

when reduced to the simplest form.

A phone company offers to monthly plans. Plan a cost $23 plus an additional $.08 for each minute of calls. Plan B cost $19 an ad
Anettt [7]

Answer:

The indifference point is 100 minutes.

Step-by-step explanation:

Giving the following information:

Plan a cost $23 plus an additional $.08 for each minute of calls.

Plan B cost $19 an additional $.12 for each minute of calls.

<u>First, we need to establish the total cost formula for each plan:</u>

Plan A= 23 + 0.08*x

Plan B= 19 + 0.12*x

x= number of minutes

<u>Now, to calculate the indifference point, we equal both formulas and isolate x:</u>

23 + 0.08x = 19 + 0.12x

4 = 0.04x

100= x

The indifference point is 100 minutes.

<u>Prove:</u>

Plan A= 23 + 0.08*100= $31

Plan B= 19 + 0.12*100= $31
