Answer:
Curly fries=$2.29 per order
Bacon=$4.79 per order
Step-by-step explanation:
let b denote bacon and f denote curly fries.
We represent the situations using inequalities as:
![2b+3f=16.45\ \ \ \ \ ...i\\\\1f+3b=16.66\ \ \ \ \ ...ii](https://tex.z-dn.net/?f=2b%2B3f%3D16.45%5C%20%5C%20%5C%20%5C%20%5C%20...i%5C%5C%5C%5C1f%2B3b%3D16.66%5C%20%5C%20%5C%20%5C%20%5C%20...ii)
#we make f the subject of the formula in ii and substitute in i:
![f=16.66-3b\\\\\#substitute \ in \ i\\\\2b+3f=16.45\\\\2b+3(16.66-3b)=16.45\\\\\\2b+49.98-9b=16.45\\\\-7b=-33.53\\\\b=4.79\\\\f=16.66-3\times 4.79\\\\=f=2.29](https://tex.z-dn.net/?f=f%3D16.66-3b%5C%5C%5C%5C%5C%23substitute%20%5C%20in%20%5C%20i%5C%5C%5C%5C2b%2B3f%3D16.45%5C%5C%5C%5C2b%2B3%2816.66-3b%29%3D16.45%5C%5C%5C%5C%5C%5C2b%2B49.98-9b%3D16.45%5C%5C%5C%5C-7b%3D-33.53%5C%5C%5C%5Cb%3D4.79%5C%5C%5C%5Cf%3D16.66-3%5Ctimes%204.79%5C%5C%5C%5C%3Df%3D2.29)
Hence, one order of curly fries costs $2.29 and one order of bacon costs $4.79
