0, 1, 3, 5, 7 which gives you 18.
Step-by-step explanation:bits still kinda blurry but I can Manage
1.
![58.99 - ( \frac{46}{100} \times 58.99)](https://tex.z-dn.net/?f=58.99%20-%20%28%20%5Cfrac%7B46%7D%7B100%7D%20%20%5Ctimes%2058.99%29)
2. I guess
![\frac{450 - 350}{450 + 350} \times 100](https://tex.z-dn.net/?f=%20%5Cfrac%7B450%20-%20350%7D%7B450%20%2B%20350%7D%20%20%5Ctimes%20100)
3. I think
(20/100 + 25/100)
