e should read: do the answers to sections a. through d. match your expectations, why or whay not?

agreene · Answer

$$c=\frac{6000}{200-2x}$$
yarp?
if so, for a-c just plug in the values they give you..
so like for a:
$$c=\frac{6000}{200-2(75)}$$

for part d. you need to find cases where the denominator = 0, or in other words, solve:
0= 200-2x
