Complete question :
Ryan is mowing lawns. It takes him an hour to mow one lawn. He has already spent 2 hours mowing lawns today. He can only mow today for a total of 5 hours at most. The given inequality can be used to find x, the number of lawns he can still mow today. Which statement is true? A. Ryan can mow no fewer than 7 additional lawns today. B. Ryan can mow no more than 3 additional lawns today. C. Ryan can mow no more than 7 additional lawns today. D. Ryan can mow no fewer than 3 additional lawns today.
Answer:
B. Ryan can mow no more than 3 additional lawns
Step-by-step explanation:
Given that :
Time taken to now 1 lawn = 1 hour = 60 minutes
Number of hours already spent mowing today = 2
He can mow at most 5 hours mowing today
Find the number of lawn x he can still mow today:
Since 1 lawn takes 1 hour to mow ;
Lawns mowed in 2 hours = 2 lawns
The most number of lawn he can mow today Given that he can only spent at most 5 hours mowing will be (5/1) = 5 lawns
Lawns mowed already + x ≤ 5
2 + x ≤ 5
x ≤ 5 - 2
x ≤ 3
Hence, Ryan can mow no more than 3 additional lawns.
