Question: Josh’s mom gives him $20 to go shopping at the mall. He buys a hat for $10 and a pencil for $2. Then he buys four cookies. If each cookie costs $1.25, how much money does Josh have left?
Answer: After buying a hat, Josh has $20 - $10 = $10. After buying a pencil, Josh has $10 - $2 = $8. The total cost of cookies is 4 * $1.25 = $5. After buying the cookies, Josh has $8 - $5 = $3. The answer is 3.
[Question]A baker is comparing the day’s sales to his daily average. He usually sells 20 pastries and 10 loaves of bread. Today, he sells 14 pastries and 25 loaves of bread. If pastries are sold for $2 and loaves of bread are sold for $4, what is the difference, in dollars, between the baker’s daily average and total for today?
[Answer]The daily average sales of pastries amounts to 20 pastries * $2 / pastry = $40. The daily average sales of bread amounts to 10 loaves of bread * $4 / loaf = $40. Therefore, the daily average is $40 + $40 = $80. Today’s sales of pastries amounts to 14 pastries * $2 / pastry = $28. Today’s sales of loaves of bread amounts to 25 loaves of bread * $4 / loaf = $100. Therefore, today’s sales amount to $28 + $100 = $128. This means the total difference between today’s sales and the daily average is $128 – $80 = $48. The answer is 48.
Q: The mayor commissioned two artists to paint 50 murals around the city. Once the work was completed, Celina was paid $1,000 more than 4 times the amount Diego got. If the mayor paid the two a total of $50,000, how much did Diego get?
A: Let d be Diego’s payment. Both artists were paid (1000 + 4 * d ) + d = 50000 dollars. This means that 5d = (50000 - 1000) dollars. Therefore Diego was paid d = 49000 / 5 = 9800 dollars. The answer is 9800.
Question: The music festival of Bassompierre begins tonight with a concert by the string orchestra "PIANISSIMO". The ticket price for adults is $26; for children, the price is half. The show starts at 9 pm and goes very well. At about 11:00 pm, the concert organizer made his accounts. There were 183 adults and 28 children who attended the show. What was the total revenue of the concert?
Answer: The total revenue from the adults is 183 x $26 = $4758. The ticket price for children is $26 / 2 = $13. The total revenue from the children is 28 x $13 = $364. The total revenue of the concert is $4758 + $364 = $5122. The answer is 5122.
