Answer:

$625 (but it's really $763.14)

Step-by-step explanation:

Use the formula I=P(1+r)^t

April=25000(1.04)^5=$30416.32

May=25000(1.0375)^6=$31179.46

$31179.46-$30416.32=$763.14

So $625 is the closest answer

Answer:

Read explanation

Step-by-step explanation:

Wow I'd love to go to that store of yours! :P Anyways if you were asking for the new discounted price I solved this equation: 12*0.8 and got $9.60. But if it was asking for <em>how </em> <em>much </em>was discounted, I would do 12*0.2 and $2.40.
