Question: Bob wants to build a pyramid out of legos with 3 levels where the bottom level has 7 legos per side and each level has one less lego per side than the level below it. How many legos total will he need?
Answer: First find the total number of legos on the bottom layer: 7 legos * 7 legos = 49 legos. Then find the number of legos per side on the next layer: 7 legos - 1 lego = 6 legos. Then find the total number of legos on the second level: 6 legos * 6 legos = 36 legos. Then find the number of legos per side on the top level: 6 legos - 1 lego = 5 legos. Then find the total number of legos on the top level: 5 legos * 5 legos = 25 legos. Then add the number of legos on each level to find the total number of legos: 49 legos + 36 legos + 25 legos = 110 legos. The answer is 110.

Q: Mason opens the hood of his car and discovers that squirrels have been using his engine compartment to store nuts. If 2 busy squirrels have been stockpiling 30 nuts/day and one sleepy squirrel has been stockpiling 20 nuts/day, all for 40 days, how many nuts are in Mason's car?
A: First find the number of nuts the two busy squirrels gather per day: 2 squirrels * 30 nuts / day / squirrel = 60 nuts / day. Then add the number the sleepy squirrel gathers each day: 60 nuts / day + 20 nuts / day = 80 nuts / day. Then multiply the number of nuts gathered daily by the number of days to find the total number of nuts gathered: 80 nuts / day * 40 days = 3200 nuts. The answer is 3200.
