The classic examples of known but unsought goods are funeral services, encyclopedias, fire extinguishers and reference books. In some cases even an airplane/helicopters can be cited as examples of unsought goods. The purchase of these goods may not be immediate and can be deferred
The mean of the data set is 14.4
This problem uses a system of equations
Let
p = cost of pencils
n = cost of pens
Then we have that
2p + 3n = 18.80
6p + 6n = 45
- 3 (2p + 3n) = 18.80 (- 3)
-6p - 9n = -56.40
6p + 6n = 45
—————————
-3n = - 11.40
n = 3.80
Sol. {A pen costs $3.80}
—> Check:
If p = $3.70 then
2(3.70) + 3(3.80) = 18.80
7.40 + 11.40 = 18.80
18.80 = 18.80
