The equation that represents this situation is:

4.50x = 75.00

where x represents the number of dolls Mariah can buy.

Answer 2

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?

Answer 3

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.

Answer 4

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?

Answer 5

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.
