Fred Salmon purchased six $1,000 bonds at 92. The bonds pay 6.5%. What was the cost of the bonds? What was the total annual inte
Hunter-Best [27]
What is the cost of the bond?
When you see that a bond was purchased "at 92", this means that the bond was purchased for 92% of the face value. Sometimes the bond purchaser will pay more than the face value (purchased a number greater than 100), generally if the interest rate is higher than the market rate. 

The cost of one bond, then, is 92% of 1,000, or $920.
Since there are 6 bonds, the total cost is 920 x 6 = $5520

What is the total annual interest?
The annual interest is the interest rate on the bond times the face value (not the cost of the bond).
The interest rate is 6.5%, so the annual interest on one bond is:
6.5% x 1000 = $65
6 bonds: $65 x 6 = $390

When we think of yield, we want to consider the real return on the bond. This is the annual interest earned divided by what the purchaser paid for it.
The purchaser paid $5520 for the bonds, and is earning $390.
390 ÷ 5520 = 7.06%.
Note that we can also calculate the return on one bond, rather than the total cost and interest of 6 bonds, and get the same result.
65 ÷ 920 = 7.06%

De un total de 24 niñas 1/4 practican natación, 1/2 juega volibol y el resto no practica ningún deporte. ¿Cuántas niñas no pract
masya89 [10]

Answer:

6 niñas no practican ningún deporte.

Step-by-step explanation:

De un total de 24 niñas, \frac{1}{4} practican natación. Esto se expresa mediante la operación matemática:

\frac{1}{4} *24

Para multiplicar una fracción por un número entero, cualquier entero n puede ser escrito como la fracción \frac{n}{1}. Entonces en este caso:

\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}

Ahora se multiplican los denominadores para obtener el denominador final y se multiplican los numeradores para obtener el numerador final:

\frac{1}{4} *24=\frac{1}{4} *\frac{24}{1}=\frac{1*24}{4*1}=\frac{24}{4}

Finalmente, se reduce el resultado hasta llegar a la forma más simple. Para obtener un resultado simplificado, se divide el numerador por el denominador.  En este caso, para reducir la fracción \frac{24}{4}, se divide 24 por 4. El resultado obtenido es 6. Esto indica que de un total de 24 niñas, 6 practican natación.

Por otro lado, de un total de 24 niños, \frac{1}{2} juegan voleibol. Esto se expresa mediante la operación matemática:

\frac{1}{2} *24

Resolviendo de manera similar a lo previamente calculado, se obtiene:

\frac{1}{2} *24= 12

Esto indica que de un total de 24 niñas, 12 practican voleibol.

Por lo que 6 niñas practican natación y 12 voleibol, siento un total de 18 niñas las que practican algún deporte. Por lo que la cantidad de niñas que no practican ningún deporte se calcula mediante:

24 niñas - 18 niñas que practican algún deporte= 6 niñas

<u><em>6 niñas no practican ningún deporte.</em></u>
