To make it quickly we can consider only those numbers which will give us a decimal of xxx.7. There are only a few numbers like this: 85.2, 88.2, 20.5.
I tried adding 85.2 to 17.5 and it gave me 102.5 - it was close but not close enough :)
So I picked 85.2 + 20.5 = 105.7 and voila :)
Ok, so you eat 1/3 of the pizza the first night. That would leave 2/3 of the pizza uneaten. 2/3 is equal to about 0.67.
You're now going to eat a quarter of what's left of the pizza. A quarter of 2/3 is 2/12 which is 1/6. Subtract 1/6 from 2/3... 4/6 - 1/6 = 3/6 = 1/2. The pizza is already half gone.
At the rate you've decided to eat the pizza, it's going to be half gone after 2 nights.
