Answer:
1. When he sold 20 slices of pizza at $1.25 each, he made $20
When he sold 50 slices of pizza at $1.25 each, he made $62.5
2. 96 slices of pizza. You would get that by dividing 120 by 1.25, as he needs to make $120, and each slice costs $1.25
The line is right in the middle of 100 and 110 degrees so the answer should be 105 degrees. This tool is called a protractor. :)
