original: \(72, new:\)60

Short Answer

Expert verified

The percentage of decreasing is 17%.

Step by step solution

01

Step 1. Given information.

We have 鈥榦riginal is$72and new is$60鈥欌赌�.

To find the percent of the change is the percent of increase or decrease and then find the change nearest to the whole percent.

02

Step 2. Apply concept.

Firstly, we find the change between original and new data then find the percent of change by the formula.

Let rbe the percent of change then,

AmountofchangeOriginalamount=r100

03

Step 3. Calculation.

Subtracting original from new:

$60鈭�$72=鈭�$12

So, it is negative then it states the percent of decrease.

Now, find the percentage of decreasing:

1272=r100鈬�r=1272100鈬�r=16100鈬�r=16.67

Hence, the percentage of decreasing is 17%.
