The maximum amount of miles that can be driven is A) 220 miles.
The similarity ratio is 20/10 = 2, so x can be found as:
10/2 = x = 5
So only 1/10 of 4000 markers arrived.
So 1/10, or 0.1 of 4000, can be found by multiplying 1/10 by 4000.
1/10 * 4000 = 400
So she received 400 markers.
Answer:
There is a constant rate of change of both money raised and distance, so the function is linear. But the variables do have a proportional relationship, and the graph includes the point (0, 0)—0 dollars will be raised by a person who runs 0 miles. So this is a proportional function.
