Using the functions presented in the example, how much can Cam expect to earn if he sells all the corn produced on 1.5 acres?

For reference: C(a) = 7500a - 1500C(a)=7500a−1500C, left parenthesis, a, right parenthesis, equals, 7500, a, minus, 1500, M(c) = 0.9c - 50M(c)=0.9c−50M, left parenthesis, c, right parenthesis, equals, 0, point, 9, c, minus, 50 and M(C(a))=6750a-1400M(C(a))=6750a−140 0

Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.

Step-by-step explanation:

Given : ,  and  

To find : How much can Cam expect to earn if he sells all the corn produced on 1.5 acres?

Solution :  

Substitute a=1.5,

Now, taking function

Substitute C=9750,

Now, taking function

Substitute a=1.5,

Therefore, Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.

i got 10.28 but that rounds up to 10.3
