Answer the following question.
Anthony keeps a bottle of vinegar in his cupboard for 2 years. Each year 20% of the vinegar evaporates. What percent of the vinegar is left after 2 years?
Step-by-step reasoning process: First find what percent of the vinegar is still in the bottle after each year: 100% - 20% = 80%. Then multiply the amount of vinegar left after one year by the percentage left after each year to find how much is left after 2 years: 80% * 80% = 64%.
The answer is 64.

Answer the following question.
Mr. Wells has a garden of flowers with 50 rows. If each row has 400 flowers and Mr. Wells cuts 60% of the flowers, how many flowers are remaining in the garden?
Step-by-step reasoning process: If there are 50 rows of flowers with 400 flowers per row, there are 50 * 400 = 20000 flowers in the garden,. Mr. Wells cuts flowers from 60% of the flowers, which is 60 / 100 * 20000 = 12000 flowers. The total number of flowers remaining in the garden is 20000 - 12000 = 8000.
The answer is 8000.

Answer the following question.
In a parking lot, there are cars and motorcycles. Each car has 5 wheels (including one spare) and each motorcycle has 2 wheels. There are 19 cars in the parking lot. Altogether all vehicles have 117 wheels. How many motorcycles are at the parking lot?
Step-by-step reasoning process: There are 19 cars at the lot, so there are 5 * 19 = 95 wheels of cars. So there are 117 - 95 = 22 wheels of motorcycles in the parking lot. Each motorcycle has 2 wheels, so that leaves us with 22 / 2 = 11 motorcycles in the parking lot.
The answer is 11.
