Answer: The sum of the series is 2,548.

In a geometric series, the values are being multiplied by a constant rate. In this series, we are started at 7 and multiplying by 3.

Our series would be:
7 21 63 189 567 1701

If we add up those values, we have a total of 2,548.

Romashka [77]

Answer:

$E=12(H)$

A person should work 32 hours to earn $384

Step-by-step explanation:

A worker's earring E are a function of the number of hour, H at a rate of 12/hr.

We need to write the function.

The function will be:

Earning is represented by E and Hour is represented by H

$E=12(H)$

Now, How many hours would a person have to work to earn 384

We are given E=384, we need to find H

Putting values in above function and finding hours H

$E=12(H)\\384=12(H)\\H=\frac{384}{12}\\H= 32$

So, A person should work 32 hours to earn $384
