None of the responses is correct.
To solve for x, you need to isolate x on one side of the equation. Here's the correct solution:
Divide both sides of the equation by 15:
15x/15 = 225/15
This simplifies to:
x = 15
Therefore, x equals 15.

To find the total number of animals at the pet shop, we need to use the information that 25% of the animals are rabbits.
Let's set up an equation to solve for the total number of animals:
0.25 * Total Animals = 12
To isolate Total Animals, divide both sides of the equation by 0.25:
Total Animals = 12 / 0.25
This simplifies to:
Total Animals = 48
Therefore, there are 48 animals altogether at the pet shop.

To find the total space on the memory card, we need to use the information that the card is only 8% full and there is 1.2 GB worth of data.
Let's set up an equation to solve for the total space:
0.08 * Total Space = 1.2 GB
To isolate Total Space, divide both sides of the equation by 0.08:
Total Space = 1.2 GB / 0.08
This simplifies to:
Total Space = 15 GB
Therefore, the total space on the memory card is 15 GB.

To find the number of books in each pile, we need to divide the total number of books by the number of piles.
Let's set up the equation to solve for the number of books in each pile:
Total number of books / Number of piles = Number of books in each pile
156 books / 4 piles = Number of books in each pile
This simplifies to:
39 books in each pile
Therefore, there are 39 books in each pile.

To find how many invitations each person has to take to the post office, we need to divide the total number of invitations by the number of people mailing invitations.
Let's set up the equation to solve for the number of invitations per person:
Total number of invitations / Number of people = Number of invitations per person
225 invitations / 5 people = Number of invitations per person
This simplifies to:
45 invitations per person
Therefore, each person, including Susan, Benjamin, and the three members of the bridal party, has to take 45 invitations to the post office.
