2/3 + 3/5m = 31/15
3/5m = 31/15 - 2/3
3/5m = 31/15 - 10/15
3/5m = 7/5
m = 7/5 * 5/3
m = 35/15 reduces to 7/3 or 2 1/3

-3c - 12 = -5 + c
-3c - c = -5 + 12
-4c = 7
c = -7/4 or - 1 3/4

In the year 2000, The U.S. Budgeted $25,003 million for Natural Resources and Environment. In 2014, they budgeted $40,156 millio
stiks02 [169]

Using it's concepts, we have that:

  • The absolute change was of $15,153 million.
  • The relative change was of 60.60%.

<h3>What is the absolute change of two values?</h3>

The absolute change between two values is given by the absolute value of the difference between two values.

In this problem, the values are of $40,156 million, which is the final value, and $25,003 million, which is the initial value, hence the absolute change is:

A = 40,156 - 25,003 = $15,153 million.

<h3>What is the relative change?</h3>

The relative change is the absolute change multiplied by 100% and divided by the initial value, hence:

(15,153/25,003) x 100% = 60.60%.
