What is the percent of change from 6,000 to 60?
Thepotemich [5.8K]

Answer: 99% decrease

Step-by-step explanation: Since the number changes from 6,000 to 60, we know that it's decreasing. Now to find the percent decrease, we divide the amount of change by the original number.

The amount of change is the difference between 6,000 and 60 and the original number is 6,000.

6,000 - 60 is 5,940 so we are left with \frac{5,940}{6,000} and dividing 6,000 into 5,940 gives us 0<em>.</em>99.

Finally, since the problem is asking us for the <em>percent</em>, we write 0.999 as a percent by moving the decimal point 2 places to the right to get 99%.

So when a number changes from 6,000 to 60, it has decreased by 99%.

GuDViN [60]

Answer:

Step-by-step explanation:

Let x represent the number of phone call that she routes.

Laylah has already spent 3 minutes on the phone and she expects to spend 1 more minute with every phone call she routes. This means that if she routes x phone calls, the total number of time that Layla would have spent on the phone is

3 + x

If she routes 23 phone calls, the total time that Layla would have spent on the phone in total is

3 + 23 = 26 minutes
