Well going with the answer mathematically, it would take 2.5 hours for 2 people to cut the grass.
4- 20
I created an equation for this one:
4x+x=100

- x= the number
- combine like terms
5x=100
x=20
5. One pretzel costs $3
Create an equation:
Mulitply 2s+p=7 by -2 so you can use elimination.
Combine equations
p=3
3/5/5
3/5/5/1
(3/5)(1/5) - flip when dividing
3/25
Pi x r x r
3.14 x 8.5 x 8.5
=226.87cm square
so the answer is B
