The graph is an illustration of a linear equation, where
- <em>The cubic feet per minute is 31.25</em>
- <em>The cubic feet per hour is 1875</em>
- <em>15931.25 cubic feet of water will be used at the water park on Tuesday</em>
<em />
From the graph, we have:
The unit rate is calculated as follows:
<em /><em> cubic feet per minute</em>
The unit rate per hour is as follows
<em /><em> cubic feet per hour</em>
The equation in hours is as follows:
Where:
---- in hours
So, we have:
<u>The water park runs 8.5 hours on Tuesday (i.e. 11am to 7:30pm)</u>
So, we have:
Hence, 15931.25 cubic feet will be used at the water park on Tuesday
