Andy can get 50 demerits in a month before getting fired. If he got 2 demerits per instance for showing up late 6 times and 15 demerits for making an inappropriate joke, how many more demerits can he get this month before getting fired? Give the rationale and then the answer.
Let's think step by step. First find how many demerits Andy got for showing up late: 2 demerits / time * 6 times = 12 demerits. Then subtract the number of demerits he's gotten so far to find how many more he can get before getting fired: 50 demerits - 12 demerits - 15 demerits = 23 demerits.. The answer is: 23.

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? Give the rationale and then the answer.
Let's think step by step. 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.

Stephanie is checking her household budget, and needs to calculate how much she has left to pay for her bills. Her electricity bill costs $60, and this is paid in full.

Let's think step by step. Stephanie has paid three - quarters of her gas bill, which is 40 * 0.75 = $30. She then made another payment, which means she has paid 30 + 5 = $35 of her gas bill. She has paid half of her water bill, which is 40 * 0.5 = $20. She has made 4 payments towards her internet bill, which is a total of 4 * 5 = $20. Overall, her bills were 60 + 40 + 40 + 25 = $165. Overall, she has made payments of 60 + 35 + 20 + 20 = $135. Therefore, she still has to pay 165 – 135 = $30.. The answer is: 30.
