Juan, Maria y Carlos fueron a un museo.

La entrada general costaba $$ por

persona, pero, por ser estudiantes, les

aplicaba un descuento de $1 por boleto.

Después del recorrido, los tres compraron

lo siguiente para comer:

. 3 combos de pollo y papas fritas a

$4 cada uno

• 3 botellas de agua a $1 cada una

• 3 mantecados de vainilla a $1 cada uno

¿Cuánto dinero pagó cada estudiante si

dividieron el total de los gastos en partes

iguales?

The question is incomplete. The complete question is as follows.

Juan, Carlos and Maria went to the museum. The entrance ticket cost $5 per person, but, as they are students, there is a discount of $1 per ticket. After, they bought: 3 combos of chicken and fries costing $4 each; 3 bottles of water costing $1 each; 3 vanilla cookies costing $1 each; How much money each student paid if they divided the costs in equal amount?

$10

Step-by-step explanation: As each students split the bill in equal parts, to find how much they spent, we can calculate how much one of the three spent.

For ticket: 5 - 1 (because of the students discount) = $4

Each combo of chicken and fries cost $4, so: combo = $4

Each bottle of water costs $1, so: water = $1

and each vanilla cookie costs $1: cookie = $1

Total spent is:

T = 4+4+1+1

T = 10

Each student spent a total of $10 for this outing.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
