The correct equation would be:
0b. A = 240 - 4h
Step-by-step explanation:
If Clayton can plow 4 acres per hour, the number of acres he can plow in 'h' hours would be 4h.
Therefore, the number of acres left to plow would be the total number of acres (240) minus the number of acres he has already plowed (4h).
Hence, the equation that represents the number of acres left to plow would be A = 240 - 4h.
