[Question]Olivia gave William 10 napkins. Amelia also gives William twice the number of napkins Olivia gave him. If William had 15 napkins before, how many napkins does he have now?
[Answer]After Olivia gave William 10 napkins, he ends up with 15 + 10 = 25 napkins. Amelia gives William twice the number of napkins given to him by Amelia which is 2 * 10 = 20 napkins. The total number of napkins William has now is 20 + 25 = 45 napkins. The answer is 45.

[Question]At the duck park, there are 25 mallard ducks and ten less than twice as many geese as ducks. Then, a small flock of 4 ducks arrived at the park and joined the birds already there. If five less than 15 geese leave the park, how many more geese than ducks remain at the park?
[Answer]Initially, twice as many geese as ducks is 25 * 2 = 50 geese. Therefore, ten less than twice as many geese as ducks is 50 - 10 = 40 geese. Then, 4 ducks arrived at the park, resulting in 25 + 4 = 29 ducks. Five less than 15 geese is 15 - 5 = 10 geese. Thus, if 5 less than 15 geese leave, then 40 - 10 = 30 geese remain. Thus, there are 30 - 29 = 1 more geese than ducks remaining at the park. The answer is 1.

[Question]For the summer, the clothing store has a 50% discount for all items. On Wednesdays, there is an additional $10.00 off on all jeans after the summer discount is applied. Before the sales tax applies, the cost of a pair of jeans is $14.50. How much was the original cost for the jeans before all the discounts?
[Answer]
Before the Wednesday discount, the cost of the jean is $14.50 + $10.00 = $24.50. Since the original price was reduced by 50%, the original cost for the jeans is $24.50 * 2 = $49.00. The answer is 49.
