Answer:
See below.
Step-by-step explanation:
Multiplying terms with exponents make the exponents add together.

Answer:
![y=0.2*4^{x}](https://tex.z-dn.net/?f=y%3D0.2%2A4%5E%7Bx%7D)
Step-by-step explanation:
Notice when x increases 1, y is 4 times the previous one, so
the function is like ![y=C*4^{x}](https://tex.z-dn.net/?f=y%3DC%2A4%5E%7Bx%7D)
To determine the constant C, put any pair of (x, y)
Use x = 0, y = 0.2, so
0.2 =
= C * 1 = C
then ![y=0.2*4^{x}](https://tex.z-dn.net/?f=y%3D0.2%2A4%5E%7Bx%7D)

Answer:
First, write 80% as 80100. Then write an equivalent ratio that has the answer in the numerator and 200 in the denominator. 100 x 2 is 200, so 80 x 2 will be the answer. 80 x 2 = 160. The answer is $160.
