You can put this solution on YOUR website! The quarterly profit earning for XYZ corporation are:
First quarter equals 25%
Second quarter equals 15%
Third quarter equals 38%
Fourth quarter equals 22%
These earning are expressed as a percent of the yearly earnings for 2007.
If the first quarter earnings were $54,000, this means that the yearly earnings must have been $54,000 / .25 = $216,000.
25% of $216,000 equals $54,000
Now that you have the yearly earnings, you can determine the earnings for each quarter.
They would be:
First quarter equals 25% of $216,000 = $54,000
Second quarter equals 15% of $216,000 = $32,400
Third quarter equals 38% of $216,000 = $82,080
Fourth quarter equals 22% of $216,000 = $47,520
Sum up the quarterly earnings to get $216,000
The question is what were the earnings in the third quarter.
the answer is $82,080.
You could have solved it directly without actually determining the yearly eaarnings as follows:
Let Y equal the yearly earnings.
.25 * Y = $54,000 which means that Y = $54,000 / .25
The third quarter earnings are equal to .38 * Y.
Since you know that Y = $54,000 / .25, then the third quarter earnings are equal to:
.38 * ($54,000/.25) which becomes (.38/.25) * ($54,000) which becomes 1.52 * $54,000 which becomes $82,080.
Third quarter earnings are $82,080.
You get the same answer either way.
