What is the percent of change from 100 to 27?73% decrease
77% decrease
77% increase
73% increase

Answers

The percent of change from 100 to 27 is a 73% decrease. The percent of change is the value of a variable to which it gains or losses its magnitude.

How to find the percent of change?

The percent of change is calculated as follows:

% change = 100 × [final value - initial value]/(initial value)

Calculation:

The initial value is 100 and the final value is 27

So, the percent of change is

% change = 100 × (27-100)/(100)

                = 100 × (-0.73)

                = -73%

The negativesign indicates a decrease from the initial value to the final value.

Therefore, the percent of change from 100 to 27 is a 73%decrease. So, option A is correct.

Your gas bill went up from $125 per month to $150 per month. What is the percent increase of your gas bill?

Answers

Increase percent on gas bill will be 20%.

What is Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Previous price of gas per month=  $125

New price of gas per month= $ 150

Now,

Increase in price of gas bill = Previous price - New price

                                            = $ 150 - $125

                                            = $25

So, The percent increase of gas bill will be calculated as;

Percent increase = Increased price / Actual price x 100

                          = $25 / $125 x 100

                          = 1/5 x 100

                          = 20%

So, Increase in percent = 20%.

Thus, Increase percent on gas bill is 20%.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that Carpet costs $15 per square yard.

We need to find that How much will it cost to carpet a room that is 180 square feet.

Cost of carpet per square yard = 15 yard

We know that 1 yard  = 3 feet.

So, the Cost of carpet per square yard = 15

The Cost of carpet 3 square feet = 15

The Cost of carpet per square feet = 15/ 3 = 5 dollar

The Cost of carpet 180 square yard  = 180 x 5

= 950 dollar

Therefore, it will cost 950 dollar to carpet a room that is 180 square feet.
