Answer:
Yes, John did write his systems of equations correctly.
Step-by-step explanation:
FedEx charges him a flat rate of $5, so the 5 stands alone in the problem, and $0.50 per pound, so the 0.5 stands with the x because it represents each pound.
UPS doesn't charge him a flat rate so there is no stand-alone number. Since they charge $2 per pound, 2 is with the x, again representing each pound.

![f(1) = - 6 \\ thus \: substitute \: in \: the \: equation \: \\ f(x) = 3x {}^{2} - 8x + c \\ - 6 = 3(1) {}^{2} - 8(1) + c \\ - 6 = 3 - 8 + c \\ - 6 = - 5 + c \\ - 1 = c \\ c = - 1 \\ therefore \: f(x) = 3x {}^{2} - 8x - 1 \\ f(1) = 3(1) {}^{2} - 8(1) - 1 \\ f(1) = 3 - 8 - 1 \\ f(1) =3 - 9 \\ f(1) = - 6](https://tex.z-dn.net/?f=f%281%29%20%3D%20%20-%206%20%5C%5C%20thus%20%5C%3A%20substitute%20%5C%3A%20in%20%5C%3A%20the%20%5C%3A%20equation%20%5C%3A%20%20%5C%5C%20f%28x%29%20%3D%203x%20%7B%7D%5E%7B2%7D%20%20-%208x%20%2B%20c%20%5C%5C%20%20-%206%20%3D%203%281%29%20%7B%7D%5E%7B2%7D%20%20-%208%281%29%20%2B%20c%20%5C%5C%20%20-%206%20%3D%203%20-%208%20%2B%20c%20%5C%5C%20%20-%206%20%3D%20%20-%205%20%2B%20c%20%5C%5C%20%20-%201%20%3D%20c%20%5C%5C%20c%20%3D%20%20-%201%20%5C%5C%20therefore%20%5C%3A%20f%28x%29%20%3D%203x%20%7B%7D%5E%7B2%7D%20%20-%208x%20-%201%20%5C%5C%20f%281%29%20%3D%203%281%29%20%7B%7D%5E%7B2%7D%20%20-%208%281%29%20-%201%20%5C%5C%20f%281%29%20%3D%203%20-%208%20-%201%20%5C%5C%20f%281%29%20%3D3%20-%209%20%5C%5C%20f%281%29%20%3D%20-%206)
