If Jaylan takes the number of stamps he has and multiplies it by 5 and then subtracts 10, he gets 275. How many stamps does he have?
Let's represent the number of stamps Jaylan has as 'x'.
The given information tells us that when Jaylan multiplies the number of stamps he has by 5 and subtracts 10, he gets 275.
So, we can write the equation as:
5x - 10 = 275
To solve for x, we can add 10 to both sides of the equation:
5x - 10 + 10 = 275 + 10
This simplifies to:
5x = 285
Finally, we can divide both sides of the equation by 5 to find the value of x:
5x / 5 = 285 / 5
x = 57
Therefore, Jaylan has 57 stamps.

5x - 10 + 10 = 275 + 10
This simplifies to:
5x = 285
Finally, we can divide both sides of the equation by 5 to find the value of x:
5x / 5 = 285 / 5
x = 57
Therefore, Jaylan has 57 stamps.
Delia spent $250 and rented a boat for 6 hours. The rental company charges a base rate of $150 for the first 2 hours, and then an hourly rate for each additional hour. How much does each additional hour of boat rental cost?
To find out how much each additional hour of boat rental costs, we need to determine the total cost of renting the boat for 6 hours and subtract the base rate for the first 2 hours.
Let's calculate the cost for the first 2 hours:
First 2 hours cost = $150
Now, let's determine the remaining cost for the additional 4 hours:
Remaining hours = Total hours - First 2 hours
Remaining hours = 6 - 2 = 4 hours
The total cost for the additional 4 hours can be calculated as:
Remaining cost = Total cost - First 2 hours cost
Remaining cost = $250 - $150 = $100
To find out how much each additional hour of boat rental costs, we can divide the remaining cost by the number of remaining hours:
Cost per additional hour = Remaining cost / Remaining hours
Cost per additional hour = $100 / 4 hours
Therefore, each additional hour of boat rental costs $25.
Let's calculate the cost for the first 2 hours:
First 2 hours cost = $150
Now, let's determine the remaining cost for the additional 4 hours:
Remaining hours = Total hours - First 2 hours
Remaining hours = 6 - 2 = 4 hours
The total cost for the additional 4 hours can be calculated as:
Remaining cost = Total cost - First 2 hours cost
Remaining cost = $250 - $150 = $100
To find out how much each additional hour of boat rental costs, we can divide the remaining cost by the number of remaining hours:
Cost per additional hour = Remaining cost / Remaining hours
Cost per additional hour = $100 / 4 hours
Therefore, each additional hour of boat rental costs $25.
