Answer:
C. 301
Step-by-step explanation:
Since the store marked up the price by 115%. You need to first find what is 100% of 140 and then 15% of 140. 100% of 140 is obviously 140. To find 15% of 140, you take 10%, which is 14, then add half of that which is 7 to 14. 15% of 140 is 21. So you add 140 and 21; it gives you 161, which is 115% of 140. Once you add 161 to 140, it gives you a total of 301.
As shown in the figures given :
For Figure 1 : perimeter = 8 units [As can be seen in the figure]
For figure 2(with 2 octagons) : perimeter = 8 × 2 - 1 = 15 units [since 1 side is common ]
For figure 2(with 3 octagons) : perimeter = 8 × 3 - 2 = 22 units [since 2 sides is common ]
If one more octagon is added
then perimeter = 8 × 4 - 3 = 29 units [since 3 sides will be common ]
