Question

at WCW productions, the number of hours a stunt double works each month cannot be more than 7 times the number of hours the star works in the same month. This month, a stunt double worked 180 hours. What is the minimum number of hours the start must work this month?

Answer 1

let
x------> the number of hours a stunt double works each month
y------> the number of hours the star works each month

we know that
x <=7y
x=180 hours
so
180 <=7y-------> 7y>=180------>y >= (180/7)----> y >=25.71 hours

the answer is
the minimum number of hours the star must work this month is 25.71
