Cinco amigos van al cine. La entrada cuesta 4,50$ dos no tienen dinero y los otros tres deciden invitarles ¿Cuanto dinero tiene que poner de mas cada uno?

Answer 1

In this problem, five friends go to the movies and two friends do not have enough money. The three friends decide to invite them and each friend needs to contribute $1.80 extra.

Step-by-step explanation:

In this problem, five friends want to go to the movies, but two of them do not have enough money to buy the tickets. The other three friends decide to invite them to join them. To calculate how much extra money each of them needs to contribute, we need to find out the total cost of the tickets and divide it equally among the five friends.

The cost of the tickets is $4.50 each, so the total cost is 5 x $4.50 = $22.50. The three friends will pay for their own tickets, so they will contribute $4.50 x 3 = $13.50. The remaining $22.50 - $13.50 = $9.00 needs to be divided equally among the five friends. Each friend will need to contribute $9.00 / 5 = $1.80.

Answer 2

Costo unitario= $3

Step-by-step explanation:

Dada la siguiente información:

Entrada= $4.5

Cantidad de entradas de más= 2

Cantidad de amigos que pagan= 3

Primero debemos calcular el total a pagas de más:

Total a pagar de más= 2*4.5= $9

Ahora, cuánto debe pagar cada uno:

Costo unitario= costo total / cantidad de personas

Costo unitario= 9/3

Costo unitario= $3
