Answer:
function
Step-by-step explanation:
Take the difference of the two options and then find the ratio, so..
50 - 20 = 30
40 - 25 = 15
ratio = 15/30 = 0.5 fifty cents per pound which means that the starting fee would be

Answer:
![-8a^{7b}](https://tex.z-dn.net/?f=-8a%5E%7B7b%7D)
Step-by-step explanation:
![(-4 a^{5b}) (2a^{2b}) = -(2^2 a^{5b}) (2a^{2b})\\](https://tex.z-dn.net/?f=%28-4%20a%5E%7B5b%7D%29%20%282a%5E%7B2b%7D%29%20%3D%20-%282%5E2%20a%5E%7B5b%7D%29%20%282a%5E%7B2b%7D%29%5C%5C)
![= -(2 ^2 \times 2) \times a^{5b + 2b}\\\\= -(2 ^{2+1}) \times a^{7b}\\\\=-(2^{3}) \times a^{7b}\\\\= - 8 a^{7b}](https://tex.z-dn.net/?f=%3D%20-%282%20%5E2%20%5Ctimes%202%29%20%5Ctimes%20a%5E%7B5b%20%2B%202b%7D%5C%5C%5C%5C%3D%20-%282%20%5E%7B2%2B1%7D%29%20%5Ctimes%20a%5E%7B7b%7D%5C%5C%5C%5C%3D-%282%5E%7B3%7D%29%20%5Ctimes%20%20a%5E%7B7b%7D%5C%5C%5C%5C%3D%20-%208%20a%5E%7B7b%7D)
