11) Jacob talked the man at the bike shop to decrease the price of a bike he
wanted to purchase. The price of a mountain bike is decreased from $150 to
$120. By what percent is the price decreased?
PLEASE HELP ME
It decreased by $30, which means 150/30. You want to reverse it, 30/150 = 0.20 (which is also 20%). This is how I do it, sorry if I couldn't explain it well.
