Answer: 22 quarters
Step-by-step explanation:
Let N be the number of nickels.
Then the number of quarters is (55-N)
The nickels contribute 5N cents to the total.
The quarters contribute 25*(55-N) cents to the total.
5N + 25*(55-N) = 715
5N + 1375 - 25N = 715
-20N = 715 - 1375 = -660
So there is 22 quarters inside the jar.
Check to see if my answer is correct-
33*5 + 22*25 = 715 cents

Step-by-step explanation:
Elasticity of demand for marijuana
(dQ/Q)/(dP/P) = -2.75
If the price drops 81%, that is dP/P=-0.81
If we re-arrange the equation
dQ/Q= -2.75 * dP/P = -2.75*(-0.81) = 2.2275
The demand will be 222.75% higher if the prices drop by 81%
