Tasha purchased an ipad for $625. a year later, it was selling for $500. what was the percent of change? a. 20% increase
b. 25% increase
c. 20% decrease
d. 25% decrease

I believe this answer is (C) 20% decrease

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
