Dracula, Frankenstein, Mummy, Gilda and Zelda are all having a Halloween party. Each of them has given an invitation to all of the others. How many invitations have been given out?
5 * 4 = ?
Each person sends out four invitations.
4X5=___number of invitations given out.
To determine the number of invitations that have been given out, we can sum up the number of invitations each character has given.
Let's break it down:
- Dracula has given an invitation to Frankenstein, Mummy, Gilda, and Zelda. That's 4 invitations.
- Frankenstein has given an invitation to Dracula, Mummy, Gilda, and Zelda. That's 4 invitations.
- Mummy has given an invitation to Dracula, Frankenstein, Gilda, and Zelda. That's 4 invitations.
- Gilda has given an invitation to Dracula, Frankenstein, Mummy, and Zelda. That's 4 invitations.
- Zelda has given an invitation to Dracula, Frankenstein, Mummy, and Gilda. That's 4 invitations.
Now, let's add up the invitations:
4 invitations (from Dracula) + 4 invitations (from Frankenstein) + 4 invitations (from Mummy) + 4 invitations (from Gilda) + 4 invitations (from Zelda) = 20 invitations.
Therefore, a total of 20 invitations have been given out in total for the Halloween party.
