Question: There are four times as many boys at Lulu's party as girls. Each boy paid twice the money that each girl paid to attend the party. If there are 40 boys at the party and each boy paid $50 to attend the party, calculate the total amount of money collected at the party.
Answer with step-by-step thinking: The total amount of money collected from the boy's payment is 40 * $50 = $2000. There are four times as many boys at Lulu's party as girls, meaning there are 40 / 4 = 10 girls at the party. since each boy paid twice the money that each girl paid to attend the party, each girl paid $50 / 2 = $25. The total amount of money collected from the girl's payment is $25 * 10 = $250. The total amount of money collected at the party is $250 + $2000 = $2250.
So the answer is 2250.


Question: Paul makes pencils, making 100 pencils a day five days a week. He started the week with 80 pencils in his stock, and during the week he sold 350 pencils. How many pencils did he have in his stock at the end of the week?
Answer with step-by-step thinking: Making 100 pencils a day, he made 100 pencils / day * 5 days / week = 500 pencils during the week. With the pencils from the stock, he got 500 pencils + 80 pencils = 580 pencils. Subtracting the ones he sold, he has 580 pencils - 350 pencils = 230 pencils.
So the answer is 230.


Question: Bill is trying to count the toddlers at his daycare, but they keep running around. He double-counts 8 toddlers and misses 3 who are hiding. If Bill thinks he counted 26 toddlers, how many are there really?
Answer with step-by-step thinking:
First subtract the 8 toddlers Bill double - counted from his count: 26 toddlers - 8 toddlers = 18 toddlers. Then add the 3 toddlers he missed to find the real count: 18 toddlers + 3 toddlers = 21 toddlers.
So the answer is 21.
