<span>The independent variable is the size of the aquarium and the dependent variable is the size of the fish population. All other variables in this scenario are held constant. Dependent variables are aspects that the researcher deliberately changes to see what will result from the change. If the food, water temperature and cleanliness are the same and the size of the aquariums is different, that makes aquarium size the independent variable.</span>
Answer:
p = $2
q = $1.6
Explanation:
If a customer buys 2 loaves he will pay p for the first and q for the second
p + q
if a customer buys a single loaf he pays p
10% less of p is expressed as
p - 0.1p
1. A customer who buys 2 loaves is charged 10% less per loaf (this means average) than a customer who buys a single loaf is expressed as
(p+q)/2 = (p - 0.1p)
(p+q)/2 = 0.9p
(p + q) = 1.8p (cross multiply so that 2*0.9)
q = 1.8p - p
q= 0.8p (equation 1)
2. If a customer buys 6 loaves of bread he will pay p for the first loaf and q for each of the remaining 5 so that
p + 5q = $10 (equation 2)
Now put substitute equation 1 into 2
p + 5(0.8p) = $10
p + 4p = 10 (add)
5p = 10
p = 2 (after dividing both sides by 5)
Now put p=2 into equation 1
q = 0.8(2)
q = 1.6
Thus p is $2

Answer:
Structured interview.
