Your profit is less than the cost of production. Thus, you actually lost 14 dollars. Your profits = -14
CD cost=17.50
Marked up=8%
So 8%of 17.50
8÷100×17.50=1.4
So add the old cd cost to the answer
=17.50+1.4=18.9 is the new cost
We know, Q = m.c.Δt
Here, m = 31 g
c= 4.186 J / g C
Δt = 65
Substitute their values,
Q = 31 * 4.186 * 65
Q = 8434.79 J
In short, Your Answer would be 8434.79 Joules
Hope this helps!
