Answer:
-12.5%
-14.29%
Step-by-step explanation:
For #2:
Original price is $2.00, that price decreased by $0.25 is $1.75. First figure out what $0.25 out of $2.00 is as a percent:
0.25/2.00 = 0.125 = 12.5%
Then, since the price DECREASED by $0.25, the percent would be negative.
For #4:
Original price is $3.50, that price decreased by $0.50 is $3.00. Like #2, you need to figure out what $0.50 out of $3.50 is as a percent:
0.50/3.50 = 0.1429 = 14.29%
Then, since the price DECREASED by $0.50, the percent would be negative.
