-32 or 4x -8

Step-by-step explanation:

-2 ( -3x + 2 ) : 6x - 4

= 6x -4 - 2 ( x + 2 )

- 2 ( x + 2 ) : - 2x -4

=6x - 4 - 2x - 4

= 6x -2x - 4 - 4

= 6x - 2x - 8

= 4x - 8

= -32  

( Im not really sure what is the answer )

( the "x" is alphabet, not "times" )

Fuel A

f(x)= 2.96*(1.04)^x I assume it is power x not multiplication by x, otherwise it would be too much increase

This is increasing function as 1.04 is > 1 and powers of 1.04 will increase as value of x increases

1.04 represents 4% increase per month

Fuel B

Price change is

3.22/3.04 ≈ 1.06

3.41/3.22 ≈ 1.06

3.61/3.41 ≈ 1.059

Price change is ≈ 6% per month

Fuel B has a greater percentage change
