Scientists want to set up and test animals in the area for West Nile. The costs to test are $2,200 for setup plus $1.50 to administer each test.
(2200 + 1.5x)/x What is the average cost to test 25 animals?250 animals??1000 animals???
(2200 + 1.5x)=2201.50 *25 =2239.00 Is this correct????
Opps I think the other one was wrong so here's my new answer: (2200 + 1.5x)=1.5*25+$2,200 =$2,237.50
your cost equation is
cost = (2200 + 1.5x)/x where x is the number of animals tested
so to test 25 animals
= (2200 + 25(1.5))/25 = 89.5
do the same for the other cases.
Very strange formula, does it find the average cost per animal to test ?
1.50 per animal. 2200.00 for set-up and 1,50 per animal ??? are you sure your right???
To calculate the average cost to test a specific number of animals, you need to use the given formula:
Average Cost = (Setup Cost + (Cost per Test * Number of Animals)) / Number of Animals
Let's calculate the average cost for testing 25 animals:
Average Cost = (2200 + (1.5 * 25)) / 25
Average Cost = (2200 + 37.50) / 25
Average Cost = 2237.50 / 25
Average Cost = 89.50
Therefore, the average cost to test 25 animals is $89.50.
Now, let's calculate the average cost for testing 250 animals:
Average Cost = (2200 + (1.5 * 250)) / 250
Average Cost = (2200 + 375) / 250
Average Cost = 2575 / 250
Average Cost = 10.30
Therefore, the average cost to test 250 animals is $10.30.
Lastly, let's calculate the average cost for testing 1000 animals:
Average Cost = (2200 + (1.5 * 1000)) / 1000
Average Cost = (2200 + 1500) / 1000
Average Cost = 3700 / 1000
Average Cost = 3.70
Therefore, the average cost to test 1000 animals is $3.70.
Based on these calculations, your previous answer of $2239 for testing 25 animals is incorrect. The correct answer is $89.50.
