a. Write the inequalities for the size of $3.00 fish that he can sell. Let x be the length of a fish he sells.b. If you only had $4.50 with you, what is the largest fish you could buy from the fisherman? Explain how you know this.

Given:
There are given that the fish is smaller than 12 inches in length for $3.00.
Explanation:
Since the fish cost $3.00, he can only afford fish smaller than 12 inches.
Let x represent the length of the fish.
Then,
(a):
According to part (a), the inequality is:
[tex]6\leq x<12[/tex]And,
(b):
The largest fish you can sell for $4.50 would be close to but not equal to 12.
Final answer:
Hence, the answer is shown below:
[tex](a).6\leqslant(x\lt12)[/tex]And,
(b). The largest fish you can sell for $4.50 would be close to but not equal to 12.
