Cyrus has been contracted to write a 500 page book. On his first day, he writes 25 pages and twice that amount on the second day. On the third day he is able to write twice the amount that he did on the second day. On the fourth day, he gets writer's block and is only able to write 10 pages. How many more pages does he need to write?
Let's think: On the second day he wrote twice the amount as the first day, which was 25 pages so 2 * 25 = 50 pages. On the third day he wrote twice the amount as he did on the second day, which was 50 pages so 2 * 50 = 100 pages. The first day he wrote 25, then 50, then 100 and 10 on the fourth day for a total of 25 + 50 + 100 + 10 = 185. He needs to write 500 pages and has written 185 which means he has 500 - 185 = 315 more pages to write.. The answer is: 315.

Hans reserved a table at a fine dining restaurant for twelve people. He has to pay a deposit for the reservation, and the deposit is a flat $20 plus an extra $3 per adult but only $1 per child. Two of the people in Hans's party are his kid cousins, and the rest are adults. How many dollars does Hans have to pay as a deposit for the restaurant reservation?
Let's think: Hans's party includes 12 - 2 = 10 adults and 2 children. The adults will cost 3 * 10 = $30 for the deposit. The children will cost 2 * 1 = $2 for the deposit. Thus, Hans has to pay 30 + 2 + 20 = $52 as a deposit for the restaurant reservation.. The answer is: 52.

Anna used four baking trays to bake cupcakes. Each tray has 20 cupcakes and each cupcake was then sold for $2. If only 3/5 of the cupcakes were sold and the rest were kept, how much did Anna earn from it?
Let's think: Anna baked 4 x 20 = 80 cupcakes. She sold 80 x 3 / 5 = 48 cupcakes. Thus, she earned 48 x $2 = $96 from it.. The answer is: 96.

A yearly book sale is held in school where students can sell their old books at a cheaper price. Two-fifths of Lovely's books can be sold for $2.50 each and the rest for $2 each. How much will Lovely earn if all 10 books were sold?
Let's think:
Lovely will sell 10 x 2 / 5 = 4 books for $2.50 each. She will sell 10 - 4 = 6 books for $2 each. Her earnings for the 4 books at $2.50 will be $2.50 x 4 = $10. Her earnings for the 6 books for $2 each will be $2 x 6 = $12. Thus, Lovely's total earning if all 10 books are sold is $10 + $12 = $22.. The answer is: 22.
