Answer:
Ok, so the answer is 3.5
Step-by-step explanation:
From what I could see it says walked for 14 around her block 4 times so your answer is 3.5 because if (Let's call her Patricia) Patricia walked around her block 4 times in 14 minutes, we have to find the unit rate, therefore we have to divide 14 by 4 as shown below
Thus your only viable solution is 3.5

Figure 1 is the original figure, while figure 2 is modified, so that a triangle and a rectangle can be easily observed.
The area of triangle and rectangle represents the total number of cubic feet of storage multiply by the number of days of storage usage.
Hence
Total Area = Area of triangle + Area of rectangle
= 30 x 10,000 + ½ 30 x (30,000 – 10,000)
= 300,000 + 300,000
= 600,000
As 10 cubic feet of storage cost $5 for a day, so total amount company have to pay
<span>= (5 x 600,000) / 10 = $300,000</span>
