Answer:
Terry was charged for 4.5 hours of labor.
Step-by-step explanation:
50x + 150 = 375
Where x = hours
50x = 375 - 150
50x = 225
Divide both sides by 50 to isolate x
x = 4.5
We must find UNIQUE combinations because choosing a,b,c,d... is the same as d,c,b,a...etc. For this type of problem you use the "n choose k" formula...
n!/(k!(n-k)!), n=total number of choices available, k=number of choices made..
In this case:
20!/(10!(20-10)!)
20!/(10!*10!)
184756
