7. The priced changed from 70 to 40. So, the % change is
(40-70)/70 = -30/70 = -0.43 or -43%
The negative value means that the price decreased. We didn't really need that for this problem, since we already knew that the change was a decrease. In other exercises, though, it may not be obvious at first, and your answer will have to reflect whether the change was positive or negative.
