Reasoning and answer: Ruth's two cousins ate a total of 2 x 1 = 2 sandwiches. So there were 3 + 2 = 5 sandwiches left before her two cousins arrived. Before her first cousin arrived, there were 5 + 2 = 7 sandwiches. Ruth and her brother had 1 + 2 = 3 sandwiches altogether. Therefore, Ruth prepared 7 + 3 = 10 sandwiches.".

On the second day, Maria sold 30 * 2 = 60 tulips. She also sold 20 * 2 = 40 roses the second day. On the third day, Maria sold only 10 / 100 * 60 = 6 tulips. Over these three days Maria sold 30 + 60 + 6 = 96 tulips. She also sold 20 + 40 + 16 = 76 roses. So on the tulips Maria earned 96 * 2 = $192. And on roses Maria earned 76 * 3 = $228. In total, over these three days, Maria has earned 192 + 228 = $420.
The answer: 420

Reasoning and answer: There are 10 tiles that are 6 inches long running the width of the bathroom so it is 10 * 6 = 60 inches long. There are 12 inches in a foot and it’s 60 inches wide so it is 60 / 12 = 5 feet wide. There are 20 tiles that are 6 inches long running the length of the bathroom so it’s 20 * 6 = 120 inches long. There are 12 inches in a foot and it’s 120 inches long so it is 120 / 12 = 10 feet wide. The square footage is l x w so the bathroom has 10 * 5 = 50 sq feet.
The answer: 50

Reasoning and answer: First subtract the cost of Mark's groceries from the amount he gives the cashier to find how much he gets in change: $7.00 - $4.20 - $2.05 = $0.75. Then subtract the value of a quarter in cents (25) and the value of a dime in cents (10) from the change amount to find how much Mark gets paid in nickels: $0.75 - $0.25 - $0.10 = $0.40. Now divide the amount Mark gets in nickels by the value per nickel in cents (5) to find how many nickels Mark gets: $0.40 / $0.05 / nickel = 8 nickels.
The answer: 8
