i really don't understand. i tried figure out. i started with the first charges: sqrt[2(20)(100))/0.05}
Suppose you have a choice of three suppliers for footballs. the first charges $100 per delivery but won't deliver more than 200 at a time; the second charges $100 also but won't deliver less than 300; the third will deliver any quantity but charges $200. Which supplier should you use? In all cases r = 20 and s=$0.05
To determine which supplier you should use, you need to calculate the total cost for each supplier based on the given conditions.
Let's start with the first supplier:
The first supplier charges $100 per delivery and won't deliver more than 200 at a time. We need to calculate the total cost considering the given conditions.
The total cost for the first supplier can be calculated using the formula: Total Cost = Delivery Cost + Cost per Football.
Given that r = 20 (representing the number of footballs) and s = $0.05 (representing the cost per football), we can use the formula:
Total Cost = Delivery Cost + (r * s)
Plug in the values:
Total Cost = $100 + (20 * $0.05)
Calculate the total cost for the first supplier:
Total Cost = $100 + ($1)
The total cost for the first supplier is $101.
Now let's move on to the second supplier:
The second supplier charges $100 but won't deliver less than 300 footballs. Similar to the first supplier, let's use the formula to calculate the total cost:
Total Cost = Delivery Cost + (r * s)
Given r = 20 and s = $0.05, we can plug in the values:
Total Cost = $100 + (20 * $0.05)
Calculate the total cost for the second supplier:
Total Cost = $100 + ($1)
The total cost for the second supplier is $101, which is the same as the first supplier.
Lastly, let's consider the third supplier:
The third supplier will deliver any quantity but charges $200. To calculate the total cost for the third supplier, we use the same formula:
Total Cost = Delivery Cost + (r * s)
Given r = 20 and s = $0.05, we can plug in the values:
Total Cost = $200 + (20 * $0.05)
Calculate the total cost for the third supplier:
Total Cost = $200 + ($1)
The total cost for the third supplier is $201.
Comparing the total costs, we observe that the first and second suppliers have the same cost of $101, while the third supplier has a higher cost of $201.
Therefore, based on the given conditions, you should choose either the first or second supplier since they have the lowest cost of $101.
