Answer:
25%
Step-by-step explanation:
500 bumper stickers sold in the first week is 100%. The bumper stickers sold in the second week is 50% more (150%).
500 / 100 = x / 150
x = 750
750 bumper stickers sold in the second week is 100%. The bumper stickers sold in the third week is 50% less (50%).
750 / 100 = x / 50
x = 375
The bumper stickers sold in the third week as a percentage of the bumper stickers sold in the first week is:
375 / 500 = x / 100
x = 75
The bumper stickers sold in the third week is 75% of the bumper stickers sold in the first week, which means there was a 25% decrease.
To do this problem:
-5y + 8 = -3y + 10 (add 3y to both sides)
-2y + 8 = 10 (subtract 8 from both sides)
-2y = 2 (divide by -2)
y = -1
I think the answer is C. I just don't know why.
-2+18=16
4-6=-2
Ans=C. (16,-2)
