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. Her gas bill was $40, and she has already paid three-quarters of this. She makes another payment of $5 towards her gas bill while checking her budget. Her water bill is $40, which she has paid half of, and her internet bill is $25, which she has made 4 payments of $5 towards. Overall, how many dollars does Stephanie still need to pay to finish paying her bills? Give me reasons, before answering the question
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. So the final answer is 30.
