do yoiu want us to rate it again? i learned this in 7th grade, and it was pretty easy.
i'm pretty sure that you take the $2.50-$1.50 to get $1, then take $1 and divide it by the original amount, $2.50, and get a 40% decrease.

Find the difference:
$2.50-$1.50=$1.00
Take $1 and divide it by $2.50:
1/2.50=.40
Take .40 and multiply it by 100:
.40*100=40%
There was a 40% decrease in the price.

starting price $2.50
ending price $1.50
difference $2.50 - $1.50 = $1.00
% decrease = difference/starting x 100%=
$1.00/$250 X 100% =
0.4 x 100% = 40% decrease

2.5/100=0.025
1.5/0.025=60
therefore it is a 40% decrease from the $2.50
