It's 253
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
Let a= times he hit 4 par
Let b = times he hit 5 par
a+b=18 => 4a+4b = 72
4a+5b=79
b=79-72=7
So a = 11
Total pool = 40 by 20, or 800 feet
Recreational = 20 by 10, or 200 feet
Subtract the recreational part of the pool from the total pool, your answer should be:
600 square feet are reserved for the swim team.
