find the common difference of the arithmetic sequence. 6, 9.4, 12.8, 16.2, . . . a. –1.6 b. 15.4 c. 1.6 d. 3.4

Hi there!

While there are no answer choices provided, here's how you can solve a problem like this.

To find the average of two numbers, you simply sum them up and divide by two!

For instance, to find the midpoint between 1 and 3, you add 1 and 3 to get 4, then divide by 2 which results in 2!

For 100 and 580, adding gives you 680, and dividing by 2 results in 340!

The average between 0.57 and 0.69 involves adding to get 1.26, then dividing by 2 yields 0.63!

Now, with percentages, for 45% and 67%, the addition gives you 112%, and dividing that by 2 will result in 56%!

So, for your answer options, just calculate the total and divide by two to determine which one results in 76%!

I hope this information helps!

La ganancia de Brad fue del 30%

Explicación adicional:

La ganancia es el dinero obtenido al vender un producto por encima de su costo original.

La fórmula para calcular la ganancia es:

Datos:

Precio de compra del paquete de bebidas energéticas = £9.25

Precio de venta por botella = £1

Precio total por 12 botellas = 1 * 12 = £12

Ganancia = Precio de venta - Precio de compra

= 12 - 9.25

= £2.75

Así, la ganancia de Brad fue de £2.75

Luego,

Porcentaje de ganancia = (Ganancia / Precio de compra) * 100

= (2.75 / 9.25) * 100

= 0.30 * 100

= 30%

La ganancia de Brad fue del 30%
