Answer:
P = 20000·0.921^t
Step-by-step explanation:
In the exponential model given, "a" is the initial value, 20000, and "b" is the year-to-year multiplier, or growth factor. It is 100% - 7.9% = 92.1% = 0.921. So, your exponential model can be written ...
192 markers
if 8 = 4% then 2=1%
so we can assume there are 200markers in the package.
8-200= 192 markers
a. (3,-2)
b. (-5,-3)
i think it A
x =2
y = - 2 x + 4
0 = - 2 x + 4
x = 2
