Question: Three siblings are born 5 years apart, each. If the eldest child is 20 years old now, what's the total of the ages of the three siblings 10 years from now?
Answer with step-by-step thinking: Ten years from now, the elder child will be 20 + 10 = 30 years old. If the elder child is 20 years old now, the second born is 20 - 5 = 15 years old, 5 years younger than the firstborn. The second - born will be 15 + 10 = 25 years old ten years from now. The total age of the first and second - born 10 years from now will be 25 + 30 = 55. The third - born who is five years younger than the second born is 15 - 5 = 10 years old. The third sibling's age ten years from now will be 10 + 10 = 20 years old. The total age of the three siblings ten years from now will be 55 + 20 = 75 years.
So the answer is 75.


Question: Ellen is in charge of parking at a golf tournament. Once the main lot is full, she must direct cars to park in the overflow lot. She must transport the patrons who parked in the overflow lot up to the main lot using a golf cart. Ellen can fit 3 patrons in a golf cart. There are 12 patrons who came in cars and 27 from a bus waiting in the overflow parking lot. How many golf carts does Ellen need to transport them?
Answer with step-by-step thinking: There are a total of 12 patrons who came in cars + 27 from a bus = 39 patrons who need a ride to the main lot. 3 patrons can fit in each golf cart, so 39 patrons / 3 in a cart = 13 total carts.
So the answer is 13.

Macy used 11 tokens which are worth 15 pitches each, so 11 tokens x 15 pitches = 165 pitches. Piper used 17 tokens x 15 pitches = 255 pitches. Together, Macy and Piper received 165 + 255 = 420 pitches. Macy hit the ball 50 times + Piper’s 55 hits = 105 total hits. Of the 420 pitches – 105 total hits = 315 misses.
So the answer is 315.
