Create a linear system to model this situation: Cheri operates a grass-cutting business. She
charges $20 for a small lawn and $30 for a large
lawn. One weekend, Cheri made $290 by cutting
12 lawns.
A. s + L = 290
20s + 30L = 12
B. s + L = 290
30s + 20L = 12
C. s + L = 12
20s + 30L = 290
D. s + L = 12
30s + 20L = 290
