An electronics company can spend no more than $4,000 on raw materials for circuit boards. The raw materials cost $10 per ounce f
or copper and $20 per ounce for silver.
To summarize the situation, a worker writes the inequality:
10c + 20s ≤ 4,000, where c is the number of ounces of copper material and s is the number of ounces of silver material.
Which graph's shaded region shows the possible combinations of raw materials the company can buy?

Answer:
Rabbit is faster than bear.
Step-by-step explanation:
Speed of rabbit or bear is determined by their rate of change of their distances with time.
The distance covered by rabbit in hours is given as:
The above equation is of the form , where,
is the rate of change of
with
.
Therefore, the rate of change of rabbit's distance with time is 30 mi/h.
Now, from the graph, the slope is given as the rise over run.
Rise is 50 miles and run is 2 miles.
So, rate of change of bear's distance with time is,
Now, 30 is greater than 25. So, rabbit is faster than bear.
