Problema Solution
Let's say that 12 men take part in a 12-week health study. They are instructed to play soccer with one another for one hour, three times per week. An indoor soccer facility charges the group $120 for each hour of field time. How much money will each man spend to rent the facility during the 12-week study? Assume that each man pays the same amount.
Answer provided by our tutors
In 12 weeks the men will play 3*12 = 36 hours soccer on the field.
Since 1 hour costs $120 the cost for 36 hours is 36*120.
The 12 men share the bill equally meaning we need to divide the total cost of 36*120 with 12:
36*120/12 = $360
Each man will spend $360 to rent the facility during the 12 week study.
