Answer:
72km
Step-by-step explanation:
alex : tomos : annabelle = 2 : 3 : 4
if tomos drove 24km
tomos ratio is 3
so 3 --> 24
<em>1 --> 8 </em>
<u>total ratios --> 2 + 3 + 4 = 9</u>
so total journey is 9 --> 9 * 8 = 72km
Answer:
The equilibrium quantity is 26.4
Step-by-step explanation:
Given


Required
Determine the equilibrium quantity
First, we need to determine the equilibrium by equating Qd to Qs
i.e.

This gives:

Collect Like Terms


Solve for P


This is the equilibrium price.
Substitute 2.4 for P in any of the quantity functions to give the equilibrium quantity:



<em>Hence, the equilibrium quantity is 26.4</em>
(1 + x) (13) = 13+6.5
13x + 13 = 19.5
13x = 6.5
x = 0.5
