Question: Stan weighs 5 more pounds than Steve. Steve is eight pounds lighter than Jim. If Jim weighs 110 pounds and the three of them crowd onto a scale at the same time, what is their total weight?
Answer with step-by-step thinking: Steve weighs 110 - 8 = 102 pounds. Stan weighs 102 + 5 = 107 pounds. Their total weight is 102 + 107 + 110 = 319 pounds.
So the answer is 319.


Question: A couple's wedding reception had 180 people. The bride and groom had each invited 20 couples from their side of the family. The remaining guests were friends. How many friends attended the reception?
Answer with step-by-step thinking: From the bride's side, 20 couples * 2 guests / couple = 40 guests attended. From the groom's side, 20 couples * 2 guests / couple = 40 guests attended. Therefore 180 guests - (40 guests + 40 guests) = 100 friends attended the reception.
So the answer is 100.


Question: Parker is 4 inches shorter than Daisy. Daisy is 8 inches taller than Reese. If Reese is 60 inches tall, what is the average height for the three of them?
Answer with step-by-step thinking:
Since Daisy is 6 inches taller than Reese, she must be 60 inches + 8 inches = 68 inches tall. Parker is 4 inches shorter than Daisy, making her 68 inches – 4 inches = 64 inches. The average height of the three of them is (60 inches + 68 inches + 64 inches) / 3 = 64 inches.
So the answer is 64.
