C: 9 ( = 3^2), 49 ( = 7^2), 81 ( = 9^2)
<h2>
Hello!</h2>
The answer is:
They spent $176 together.
<h2>
Why?</h2>
We are given an expression which represents the money spent for each girl, it's a function of time and it will show how much they can spend in terms of hours.
Assuming that you have committed a mistake writing the equation, otherwise, the given options would not fit, the expression is:

Now, from the statement we know that the function represents how much money each girl spent, so, if we need to calculate how much money they will spend together, we need to multiply the expression by 2, so we have:

Then, calculating the spent money for 2 hours, we need to substitute the variable "x" with 2.
Calculating we have:


Hence, we have that they spent $176 together.
Have a nice day!

Answer:
Leaving it in Radical form
Step-by-step explanation:
You cannot write out the entire real decimal without having to round because it is a never ending decimal like pi. If you are looking to type it into a calculator then radical form is best. However, if you are looking to add it to a decimal then converting to a decimal to show your work would be better than showing a radical.
