1 because you have 4 quarts in a gallon and 4•3=12 and 4•2=8+3=11 then subtract that and get 1
Answer:
Marginal cost refers to the increase or decrease in the cost of producing one more unit or serving one more customer.
Step-by-step explanation:
Definition: Marginal cost is the additional cost incurred for the production of an additional unit of output. The formula is calculated by :
Marginal Cost = (Change in the total cost)/(Change in the product output)
Answer:
Let D represent the average rate of change between 1990 and 1999
D ≈ 33%
Step-by-step explanation:
412+412×(Ｄ÷100 )= 549
⇔ 412×(Ｄ÷100) = 549 - 412
⇔ 412×(Ｄ÷100) = 137
⇔ Ｄ÷100 = 137÷412
⇔ Ｄ÷100 = 0.332524271845
⇔ D = 33.2524271845.

We are given ratio 27 to 30 that is 27:30.
We need to find the 10% using the rate 27:30.
27:30 could be written in fraction form as 27/30.
On dividing 27/30, we get 0.9.
Now, on multiplying 0.9 by 100, we get 90.
Therefore, 27/30 gives us 90%.
<em>In order to find the 10%, we need to subtract 27/30 from 1 because 1 represents 100%.</em>
1-27/30 = 30/30 -27/30 = 3/30.
<h3>Therefore, 3 is 10% of 30.</h3>
