Answer 1

Answer:

$15

Step-by-step explanation:

Can't help you with the drop down, as we need to know the info for Station A to be able to compare it with Station B, however, the cost for charging a car at Station B for 4 hours is:

use f(x) = 3x + 3  as the value of x = 4 falls in this function's interval

So f(4) = (3 x 4) + 3 = 15

So it will cost $15 for a car to charge for 4 hours at Station B.
