Week 1=50
week 2= 50×2=100
week 3=100×2=200
week 4=200×2=400
week 5=400×2=800
week 6=800×2=1600
week 7=1600×2=3200
week 8=3200×2=6400
so the answer is 6400
I think it is B. Hope this helps!
70 + 98 + 83 + 66 + 41 = 358
358 / 5 = 71.6
70 + 98 + 83 + 66 + 41 + 81 = 439
439 / 6 = 73.166...
Therefore, the correct answer to this problem is answer A.
