Answer:
a. p = (1/5)q
b. q = 50
c. p = (7/5)
Explanation:
a. p varies directly with q can be written as:
p = kq
where k is a fudge factor that relates the exact relationship between the 2 (p and q). When p changes, does q change by the dsame rate? We don't know, yet . .
We are then told that when p is 6, q is 30.
6 = k*30
That means k = (1/5)
Let's rewrite the relationship for use in (b):
p = (1/5)q
b. Find q when p is 10:
10 = (1/5)q
q = 50
c. Find p when q is 7:
p = (1/5)q
p = (1/5)*7
p = (7/5)
