Hi.
What we need to do here is write an equation that shows how the price for the first two hours plus the number of additional half-hours adds up to what can be spent - $600.
- We know that the first two hours are $350.
- We know that each subsequent half-hour is $50.
- We know we can spend no more than $600.
We're going to use the letter "x" to represent the number of half-hour segments we can buy.
Here's the equation:
350 + 50x = 600
Now we can solve for x:
50x = 250
x = 5
We can rent the boat for five additional half-hour segments beyond the initial two-hour rental period.
