a stadium must have 10 attendants at the stadium parking lot and two each at the satellite lots. each attendant makes $10/hour. if the stadium and all five satellite lots open two hours before the game, which lasts three hours, and close two hours after the game, what is the labor cost for parking? $340 $700 $1,000 $1,400
Answer
Explanation:
Step1: Calculate total number of attendants
The stadium parking - lot has 10 attendants and there are 5 satellite lots with 2 attendants each. So the total number of attendants is $10 + 5\times2=10 + 10 = 20$.
Step2: Calculate total number of hours worked
The stadium and satellite lots are open 2 hours before the game, the game lasts 3 hours, and they are open 2 hours after the game. So the total number of hours is $2 + 3+2=7$ hours.
Step3: Calculate total labor cost
Each attendant makes $10 per hour and there are 20 attendants working for 7 hours. So the total labor cost is $20\times10\times7 = 1400$.
Answer:
$1400$
