En una tienda se anuncia la rebaja de 20% en todos sus artículos. Rafael elije una camisa y al llegar a la caja le informan que esa camisa, por traer etiqueta roja, cuenta con un descuento adicional del 15%. Si Rafael pago $510.00, ¿cual era él precio de la camisa sin los descuentos?

9514 1404 393

  $750

Step-by-step explanation:

The 20% discount multiplies the price by (1 - 20%) = 0.80.

The 15% discount multiplies the price by (1 - 15%) = 0.85.

After applying the discounts to the initial price P, we have ...

  P(0.80)(0.85) = $510

  P = $510/(0.80·0.85) = $750

The price before discounts was $750.

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
