Answer the following question.
There are 516 cars in a parking lot. One-third are blue, one-half are red, and the rest are black. How many black cars are on the lot?
Step-by-step reasoning process: Blue = 516 * (1 / 3) = 172 cars. Red = 516 * (1 / 2) = 258. Black = 516 - (172 + 258) = 86. There are 86 black cars on the lot.
The answer is 86.

Answer the following question.
Porter is a painter who creates beautiful paintings of wild animals. Most recently, he painted a mural of a pack of wolves standing on a snowy-white mountainside underneath a full moon. He put the painting up for auction and it sold for $1000 less than five times more than he had made on his previous painting. If he received $44,000 for the sale of his most recent painting, how much, in dollars, did he make for selling his previous painting?
Step-by-step reasoning process: If $44,000 is $1000 less than five times more than he had made on his previous painting, then $44,000 + $1000 = $45,000 is five times what he made on his previous painting. If $45,000 is five times what he made for his previous painting, then he made $45,000 / 5 = $9,000 for selling his previous painting.
The answer is 9000.

Answer the following question.
Ian used a grocery delivery app to have his groceries delivered. His original order was $25 before delivery and tip. He noticed that 3 items changed on his order. A $0.99 can of tomatoes was replaced by a $2.20 can of tomatoes, his $1.00 lettuce was replaced with $1.75 head of lettuce and his $1.96 celery was replaced with celery that cost $2.00. Delivery and tip came to a total of $8.00. How much is his new bill now, with the food substitutes and delivery/tip?
Step-by-step reasoning process: He ordered a can of tomatoes for $0.99 but they subbed with one that cost $2.20 for a difference of 2.20 - .99 = $1.21. He ordered lettuce for $1.00 but they subbed with one that cost $1.75 for a difference of 1.75 - 1.00 = $0.75. His celery for $1.96 but they subbed with one that cost $2.00 for a difference of 2.00 - 1.96 = $0.04. That's an additional charge of 1.21 + .75 + .04 = $2.00 in groceries. His additional charges of $2.00 and the delivery / tip of $8.00 add 2 + 8 = $10.00 to the order. His original order was $25 and they added $10.00 so his new order is 25 + 10 = $35.00.
The answer is 35.

Answer the following question.
Jess and her family play Jenga, a game made up of 54 stacked blocks in which each player removes one block in turns until the stack falls. The 5 players, including Jess, play 5 rounds in which each player removes one block. In the sixth round, Jess's father goes first. He removes a block, causing the tower to almost fall. Next, Jess tries to remove another block knocking down the tower. How many blocks did the tower have before Jess's turn?
Step-by-step reasoning process: In each round, the 5 players removed a total of 5 * 1 = 5 blocks. In the 5 rounds played, the players removed a total of 5 * 5 = 25 blocks. Adding the block removed by Jess's father in the sixth round, a total of 25 + 1 = 26 blocks were removed. Before the tower fell, there were 54 - 26 = 28 blocks.
The answer is 28.
