Q: If we assume all thirty 4-wheel drive cars in the parking lot have their spare tire with them, how many tires are in the parking lot?
A: Each car has 4 tires + 1 spare = 5 tires. If there are 30 cars in the parking lot and each one has 5 tires, then the total number of tires is 30 * 5 = 150 tires. The answer is 150.
Question: Allen is 25 years younger than his mother. In 3 years, the sum of their ages will be 41. What is the present age of Allen's mother?
Answer: In 3 years, the sum of their present ages will be added by 3 (from Allen) + 3 (from her mother) = 6. So, the sum of their present ages is 41 - 6 = 35. Let x be the present age of Allen's mother and x - 25 be the present age of Allen. So the equation using the sum of their present ages is x + x - 25 = 35. By combining like terms, the equation becomes 2x = 60. Hence, Allen's mother is x = 60 / 2 = 30 years old now. The answer is 30.
[Question]At an auction event, the price of a TV, whose cost was $500, increased by 2/5 times its initial price. The price of a phone, which was $400, also increased by 40% from its original price. If Bethany had taken both items to the auction, calculate the total amount she received for the items after the sale at the auction.
[Answer]If the TV's original price was $500, at the auction, its price increased by 2 / 5 * $500 = $200. The total price at which the TV was sold at the auction is $500 + $200 = $700. The price of the phone also increased at the action, a 40% increase which is 40 / 100 * $400 = $160. The total price that the phone was sold for after the auction is $400 + $160 = $560. In total, the TV and the phone sold for $700 + $560 = $1260 at the auction. The answer is 1260.

Q: Jane's mother agreed to pay her $.50 for every flower bulb that Jane planted. Jane planted 20 tulip bulbs and half that amount of iris bulbs. She also planted 30 daffodil bulbs and three times that amount of crocus bulbs. How much money did Jane earn?
A:
20 tulip bulbs at $.50 each is 20 * .50 $10.00. She planted half that amount of iris' so 20 / 2 = 10 bulbs. 10 iris bulbs at $.50 each is 10 * .50 = $5.00. 30 daffodil bulbs at $.50 each is 30 * .50 = $15.00. She planted three times that amount of crocus bulbs to 30 * 3 = 90 bulbs. 90 crocus bulbs at $.50 = $45.00. All total, she earned 10 + 5 + 15 + 45 = $75.00. The answer is 75.
