Answer:
$4
Step-by-step explanation:
Discount is a form of consideration in price or amount given to a customer on a sale of goods. It can be deduced from the question that;
The original price of each plant = $x
Number of plants purchased = 20
Price of the number of plants purchased without discount = $20x
Amount paid for the 20 plants with discount = $(20x - 80)
Thus,
The discount on the 20 plants = $80
Discount on each plant =
=
= $4
Discount on each plant = $4
Therefore, each plant was discounted by $4.
First find the characteristic solution. The characteristic equation is
which as one root at
of multiplicity 2. This means the characteristic solution for this ODE is
For the nonhomogeneous part, you can try a particular solution of the form
which has derivatives
Substituting into the ODE, the left hand side reduces significantly to
and it follows that
Therefore the particular solution is
and so the general solution is the sum of the characteristic and particular solutions,
