Find the absolute change and the percentage change for the given situation.120 is decreased to 18

Sagot :

The absolute change is defined as:

[tex]V_2-V_1[/tex]

where V1 and V2 are the initial and final values, respectively.

Plugging the values given we have that:

[tex]18-120=-102[/tex]

Therefore the absolute change is -102. (The minues sign indicate a decrease)

The percentage change is given by:

[tex]\frac{V_2-V_1}{\lvert V_1\rvert}\cdot100[/tex]

plugging the values given we have:

[tex]\frac{18-120}{\lvert120\rvert}\cdot100=-\frac{102}{120}\cdot100=-0.85\cdot100=85[/tex]

Therefore the percentage change is -85% (Once again the minus sign indicate a decrease)
