A. 4 B. 8 C. 12 D. 16
Explanation: Let x be the number of bottles necessary.More mats, more weavers (Direct Proportion).There will be more days, and there will be more mats (Direct Proportion).Days 4 : 8 Wavers 4 : 8 Wavers 4 : 8 Wavers 4 : 8 Wavers 4 : 8 Wavers 4 : 8 Wavers 4 : 8 Wavers 4 8 x 8 x 4 x 4 x 4 x4,x = (8 x 8 x 4) x = (8 x 8 x 4) x = (8 x 8 x (4 x 4),x equals 16.
