Answer: 4.5 hours.
Explanation:
Hi, to answer this question we have to write an inequality with the information given;
Cost: 30h+65 (h= hours)
So, the cost must be less or equal to the money that Brianna can spend.(200)
Mathematically speaking:
30h+65 ≤ 200
Solving for h
30h≤ 200 -65
30h ≤ 135
h ≤ 135/30
h≤ 4.5
She can rent the boat for 4.5 hours.
