To find the different ways to display the boxes, you will find all the different ways you can make an array of 12.
12 x 1 and 1 x 12
2 x 6 and 6 x 2
3 x 4 and 4 x 3
There are 6 possibilities.
So you add 7 every time so,
28+7=34
34+7=41
if he continues his pattern he will have done 41 sit-ups on Friday
4/7=N/12 cross multiply
7N=4*12
7N=48
N=48/7
So your answer is 6 6/7 or 6.8571428
