Question

If q is directly proportional to ip - 1) and q = 20
when p = 3, find the values of p when q = 80.​

Answer 1

Answer:

Explanation:

the initial statement is q∝1p

to convert to an equation multiply by k the constant

of variation

⇒q=k×1p=kp

to find k use the given condition

q=kp⇒k=qp=32×72=108

equation is ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯∣∣∣22q=108p22∣∣∣−−−−−−−−−−−−−
