multiply 20 x -9
= -180

then it becomes a-10=-180
                             +10  +10
a=-170

Salsk061 [2.6K]

Answer:

  • No

Step-by-step explanation:

  • <em>Percent change is the difference in numbers divided by initial number converted to percent value.</em>

<u>Percent increase:</u>

  • (70 - 50)/50*100% = 40%

<u>Percent decrease:</u>

  • (70 - 50)/70*100% = 28.57%

<u>Compare:</u>

  • 40% ≠ 28.57%
