[Question]: Lillian went out to forage for mushrooms with her handy guidebook. She found 32 mushrooms and used her guidebook to identify which ones were poisonous and which were safe to eat. In the end, she had 9 mushrooms she could safely eat for dinner. Of the rest, she identified twice the amount she ate as poisonous, and a remaining bunch she was uncertain about. How many mushrooms was she uncertain were safe or poisonous?
[Answer]: Lillian found 9 of the mushrooms were safe, so there were 32 - 9 = 23 that she found poisonous or uncertain. She knew twice the amount she ate were poisonous, so she found 9 * 2 = 18 poisonous mushrooms. Thus, she was uncertain about 23 - 18 = 5 mushrooms.
So the answer is 5.

[Question]: Tanesha needs to buy rope so cut into 10 pieces that are each six inches long. She sees a 6-foot length of rope that cost $5 and also sees 1-foot lengths of rope that cost $1.25 each. What is the least she has to spend to get the rope she needs?
[Answer]: She needs 60 inches of rope because 10 x 6 equals 60. The six - foot length of rope is 72 inches long because 6 x 12 = 72. The six - foot length of rope would give her 12 pieces because 72 / 6 = 12. The six - foot length is long enough because 12 > 10. Each 1 - foot rope equals 12 inches. She would need 5 of the 1 - foot ropes because 60 / 12 = 5. If she bought one - foot ropes it would cost $6.25 because 5 x 1.25 = 6.25. The cheapest rope to buy is the 6 - foot rope because 5 < 6.25.
So the answer is 5.

[Question]: Between them, Mark and Sarah have 24 traffic tickets. Mark has twice as many parking tickets as Sarah, and they each have an equal number of speeding tickets. If Sarah has 6 speeding tickets, how many parking tickets does Mark have?
[Answer]:
First figure out how many total speeding tickets the two people got by adding the 6 speeding tickets Sarah got to the equal number (6) that Mark got: 6 + 6 = 12. Now subtract the combined number of speeding tickets from the total number of tickets to find the combined number of parking tickets: 24 - 12 = 12. Now express Mark's number of parking tickets in terms of the number of parking tickets Sarah got: m = 2s. We know that m + s = 12, so substitute in the value of m from the previous step to get 2s + s = 12. Combine like terms to get 3s = 12. Divide both sides of the equation to get s = 4. Now multiply the number of parking tickets Sarah got by 2 to find the number Mark got: 4 * 2 = 8.
So the answer is 8.
