Find each percent change. Round to the nearest tenth of a percent. State if it is an increase or decrease. From 79 miles to 84 m
PolarNik [594]

Answer:

the answer is d.

Step-by-step explanation:

first, you want to use the formula,

new value - original value

<u>____________________</u>

         original value              * 100

you see that 84 is the new value and 79 would be the original value. substitute the numbers in. this is a increase since you will get a positive value.

84 - 79

<u>______</u>

   79      * 100

now we solve it.

5

<u>__</u>

79  * 100

you can either solve the fraction first then multiply that by 100 or multiply the numerator by 100 first then divide that by 79, each way works.

500

<u>____</u>

 79   =  approximately 6.3% increase (this is not a exact value, just rounded)

      or

5

<u>__</u>

79  = approximately 0.063 (this is not a exact value, just rounded)

0.063 * 100 = 6.3% increase
