Answer:
94.5%
Step-by-step explanation:
Percent decrease can be represented as
[original price] * percentage = [new price]
When trying to find the percentage, you can manipulate the equation by dividing both sides by the original price to get:
percentage = [new price] / [original price]
In this case, this is represented by 192300/203400, or 94.5%
2.5z^2+3z+4.2
0.84 is the correct answer.
Add 0 and 0 which is 0. Add 8 and 6 which is 14. And 3 + 1 + 4 which is 8. Put that all together and the answer is 0.84. Hope it helps!!!!
