Answer:
C
Step-by-step explanation:
so m is less than o and m is less than n so that means m is the shortest angle (look at the picture) as you see NO is the longest side since theres only one answer that has NO as the first choice it has to be that one.
By setting up a system of equations we can easily solve this problem. Let's denote Jane's working hours with x and Jack's working hours with y. Since they don't want to work more than 65 hours, the first equation is x+y=65. The second equation is 14x+7y=770. By solving this system of equation 
, we find that y=20 hours, which is Jack's maximum working hours.
