Answer:
Step-by-step explanation:
First, we write the rental cost with each company:
Company A
Company B
Where m: miles travelled
Now, we need to find "number of miles in a day at which the rental costs for Company A and Company B are the same". This means Pa = Pb. Then:
Solving the equation for m by taking 0.2m and 60 on both sides:
Finally, dividing 0.5 on both sides:
Answer:
Where the set
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
A. When x = 0 (at the y-intercept),
f(x) = 3 . 9^0
= 3 * 1
= 3 so the y-intercept is (0, 3).
The total is $87.2 you have to first change the percentage to a decimal so 0.09x80=87.2
