Let's break down the problem step by step:

1. **Initial price of the coffee maker**: $110
2. **Coupon discount**: 30% off

   To calculate the price after applying the 30% off coupon:
   \[
   \text{Discounted price} = 110 \times (1 - 0.30) = 110 \times 0.70 = 77
   \]
   So, the price after the coupon is $77.

3. **Mail-in rebate**: $10

   After applying the rebate, we subtract $10 from the discounted price:
   \[
   \text{Final price} = 77 - 10 = 67
   \]

Thus, the final price Emily pays is **$67**.

1. How would the final price change if the coupon was 20% instead of 30%?
2. What if Emily received a 25% discount and the rebate was only $5?
3. How would the final price change if the original price was $120?
4. What is the total percentage discount Emily received after applying both the coupon and the rebate?
5. How can Emily calculate the price if she also has to pay 8% sales tax before the rebate?

### Tip:
When applying a percentage discount, multiply the original price by the percentage left after the discount. For example, with a 30% discount, multiply the original price by 0.70 (100% - 30%).

Emily buys a new coffee maker that costs $110. She uses a 30% off coupon and then applies for a $10 mail-in rebate. What is the final price she pays after using the coupon and receiving the rebate?
