Final answer:
The value of x that makes the cost of renting a paddle boat and the cost of renting a kayak the same is 4 hours.
Step-by-step explanation:
To find the value of x that makes the cost of renting a paddle boat and the cost of renting a kayak the same, we need to set the two equations equal to each other and solve for x. So, we have:
12x + 15 = 15x + 3
Subtracting 12x from both sides:
15 = 3x + 3
Subtracting 3 from both sides:
12 = 3x
Dividing both sides by 3:
x = 4
Therefore, the value of x that makes the statement true is 4 hours.
