Answer:
Let, the c.p be x.
Given,
profit % = 20%
S.P = rs 816
c.p = x
We know,
profit = p% of c.p
= * x
=
now,
C.p = profit + s.p.
x = + 816
x =
5x = x + 4080
5x-x = 4080
4x = 4080
x =
x = Rs 1080
Hence, the c.p is Rs. 1080
The solution to the system of inequalities is (0.667, 5.333)
<h3>How to graph the inequalities?</h3>The system of inequalities is given as:
y > 2x + 4
x + y ≤ 6
Next, we plot the graph of the system using a graphing tool
From the graph, both inequalities intersect at
(0.667, 5.333)
Hence, the solution to the system of inequalities is (0.667, 5.333)
