..
Step-by-step explanation:
a =
⇒ 670
b =
⇒ 301600
c =
⇒ 560
Since the figures are similar, we can establish a rule of three as follows.
We know that the area of the smaller figure is

, and its volume is

. We also know that the area of the larger figure is

; since we don't now its volume, lets represent it with

:



We can conclude that the volume of the larger figure is

; therefore, the correct answer is
a.
$15,000+$6,500+$23,000+$20,500+$5,000=$70,000
$70,000+$40,000=$110,000
$110,000-$82,000=-$28,000
economic profit is -$28,000
$82,000-$70,000=$12,000
accounting profit is $12,000
