b) what is the annual cost of fuel for the infiniti?

The Prius is the answer 892.49 for year and Infiniti is 2233.33

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
