Answer:
15 business class and 12 economy class
Step-by-step explanation:
15 + 12 = 27
15 * 700 = 10500
12 * 375 = 4500
$10500 + $4500 = $15,000

Answer:
![f^{-1}(x)=4(x+5)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D4%28x%2B5%29)
Step-by-step explanation:
So we have the function:
![f(x)=\frac{x}{4}-5](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7Bx%7D%7B4%7D-5)
To find the inverse of a function, switch f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:
![x=\frac{f^{-1}(x)}{4}-5](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bf%5E%7B-1%7D%28x%29%7D%7B4%7D-5)
Add 5 to both sides:
![x+5=\frac{f^{-1}(x)}{4}](https://tex.z-dn.net/?f=x%2B5%3D%5Cfrac%7Bf%5E%7B-1%7D%28x%29%7D%7B4%7D)
Multiply both sides by 4:
![f^{-1}(x)=4(x+5)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D4%28x%2B5%29)
And we're done!
Hope this helps!
Length (L): 2w + 6
width (w): w
Perimeter (P) = 2L + 2w
240 = 2(2w + 6) + 2(w)
240 = 4w + 12 + 2w
240 = 6w + 12
228 = 6w
38 = w
Length (L): 2w + 6 = 2(38) + 6 = 76 + 6 = 82
Answer: width = 38 ft, length = 82 ft
Ooo I’ll give it a go! Give me a few minutes
