I’m not sure but u multiply 2.5 by 3.8 to get amount she has to pay for GB. Since it free texts so 2.5 • 3.8 = $9.5 plus $15 which give $24.5
I could be wrong..
It would equal
-53x+211y
but thats not one of the choices
Answer:
The value of n is 5/3 .
Step-by-step explanation:
You have to apply Indices Law,
![\sqrt[n]{a} \: ⇒ \: {a}^{ \frac{1}{n} }](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7Ba%7D%20%20%5C%3A%20%E2%87%92%20%5C%3A%20%20%7Ba%7D%5E%7B%20%5Cfrac%7B1%7D%7Bn%7D%20%7D%20)

So for this question :
![{( \sqrt[3]{3}) }^{5}](https://tex.z-dn.net/?f=%20%7B%28%20%5Csqrt%5B3%5D%7B3%7D%29%20%7D%5E%7B5%7D%20)



Simply just plug in the value per seat to the number of seats.
20000(17.50) + 25000(10.75) = 350000 + 268750 = $618,750 if all the seats were sold out.
