Brandon’s rentals charges $ 25 per hour to rent a Windsufer and a wet suit. Wendy’s charges $20 per hour plus $15 extra for a wet suit. Find the number of hours for which the total charges for both would be the same.

To find the number of hours for which the total charges for both rentals would be the same, we need to set up an equation and solve for the unknown variable, which is the number of hours.

Let's assume the number of hours for which the total charges are equal is 'h'.

For Brandon's rentals, the total charge for h hours would be:
Total charges = $25/hour * h hours = $25h

For Wendy's, the total charge for h hours would be:
Total charges = $20/hour * h hours + $15

Now, we can set up an equation to find the value of 'h' when the total charges for both rentals are equal:

$25h = $20h + $15

Subtracting $20h from both sides:
$25h - $20h = $15

Simplifying the equation:
$5h = $15

Dividing both sides by $5:
h = $15 / $5

Therefore, the number of hours for which the total charges for both rentals would be the same is 3 hours.
