Reasoning and answer: His income tax is 10% of 500 which is 500 * 10% = $50. His tithe costs 10% of $500 which is 500 * 10% = $50. The total expenses are 50 + 55 + 50 = $155. He is then left with $500 - $ 155 = $345.
The answer: 345

If there are 600 pines, there are 20 / 100 * 600 = 120 more redwoods than pine trees in the national park. In total, there are 120 + 600 = 720 redwoods in the national park. Altogether, there are 720 + 600 = 1320 pines and redwoods in the national park.
The answer: 1320
Reverse engineering the question: In a national park, the number of redwoods is 20% more than the number of pines. If there are 600 pines in the national park, calculate the total number of pines and redwoods that are there.


Reasoning and answer: Faith earns $13.50 x 8 = $108 per day. Since she works 5 days a week, she earns 5 x $108 = $540 per week. She gets an additional 2 x $13.50 = $27 per day for the overtime pay. She earns a total of $27 x 5 = $135 additional pay for her weekly overtime. Therefore, Faith earns $540 + $135 = $675 per week.
The answer: 675
