Tyler has $100. If he buys 8 scissors for $5 each and 10 erasers for $4 each, how much of his money remains? Give the rationale and then the answer.
Let's think step by step. 8 * $5 = $40 is the price of 8 scissors. 10 * $4 = $40 is the price of 10 erasers. You can find the total price by adding the cost of the scissors and erasers: $40 + $40 = $80. $100 - $80 = $20 is the remaining amount of his money.. The answer is: 20.

Shem makes 2.5 times more money per hour than Kem. If Kem earns $4 per hour, how much does Shem earn for an 8-hour workday? Give the rationale and then the answer.
Let's think step by step. Shem earns $4 x 2.5 = $10 in an hour. So, Shem earns $10 x 8 = $80 for an 8 - hour workday.. The answer is: 80.

A boat carrying 20 sheep, 10 cows and 14 dogs capsized. 3 of the sheep drowned. Twice as many cows drowned as did sheep. All of the dogs made it to shore. How many total animals made it to the shore? Give the rationale and then the answer.
Let's think step by step. The boat had 20 - 3 = 17 sheep make it to shore. 3 sheep drowned, so 2 * 3 = 6 cows drowned. 10 cows on the boat - 6 drowned = 4 cows made it to the shore. 17 sheep + 4 cows + 14 dogs = 35 animals made it to shore.. The answer is: 35.
