Step-by-step reasoning process: They spent $8 each on cheeseburgers and milkshakes because 3 + 5 = 8. They spent $16 on these items in total because 2 x 8 = 16. They spent $24 on their meal because 16 + 8 = 24. They had $30 to start because 24 / .8 = 30. His cousin had $10 because 30 - 20 = 10.
The question and answer:
Question and answer: Jim and his Cousin are out at a restaurant. They each order a cheeseburger and milkshake. They also split an order to cheese fries. A cheeseburger is $3. A milkshake is $5. Cheese fries are $8. They spend 80% of their combined money. If Jim brought $20 how much did his cousin bring?
The answer is 10

Step-by-step reasoning process: A quarter of the balls are red and therefore there are 360 x (1 / 4) = 90 red balls. When you remove the red balls from the ball pit there are 360 - 90 = 270 remaining balls. A fifth of the remaining balls are blue, and therefore there are 270 x (1 / 5) = 54 blue balls. The total of red and blue balls equals 90 + 54 = 144 balls. When you remove the red and blue balls from the total there are 360 - 144 = 216 balls that are neither red nor blue.
The question and answer:
Question and answer: There are 360 balls in the ball pit. If a quarter of the balls in the ball pit are red and a fifth of the remaining balls are blue. How many of the balls are neither red nor blue?
The answer is 216

Step-by-step reasoning process: He has 60 - 20 = 40 kilograms of mangoes left after selling them to the market. Colby sold 1 / 2 x 40 = 20 kilograms of mangoes to the community. Therefore, Colby still has 20x8 = 160 pieces of mangoes.
The question and answer:
