[Question]Dexter went to the mall and saw that Apple products are on sale. He wants to buy an iPhone 12 with a 15% discount and an iWatch with a 10% discount. The price tag shows that an iPhone 12 costs $800 while an iWatch costs $300. Upon check out, he will receive a further 2% cashback discount. How much would the items cost in total after the discount and cashback?
[Answer]The discount for an iPhone 12 is $800 x 15 / 100 = $120. So, the iPhone will now cost $800 - $120 = $680. The discount for an iWatch is $300 x 10 / 100 = $30. So, the iWatch will now cost $300 - $30 = $270. The total cost of the iPhone and iWatch is $680 + $270 = $950. The cashback will be $950 x 2 / 100 = $19. Thus, Dexter will only pay $950 - $19 = $931. The answer is 931.

[Question]Donna worked 2 hours every morning walking dogs in her neighborhood for $10.00 an hour. 5 days a week, after school, she worked at a card shop for 2 hours and made $12.50 an hour. On the weekends, she usually made $10.00 an hour babysitting and was guaranteed 4 hours every Saturday from her neighbor. How much money did she make over 7 days?
[Answer]She makes $10.00 an hour for 2 hours walking dogs so she makes 10 * 2 = $20.00 every morning. Over 7 days she makes 7 * 20 = $140.00 a week. She makes $12.50 for 2 hours working at a card shop so she makes 12.5 * 2 = $25.00. She works there 5 days a week so she makes 5 * 25 = $125.00 a week. She also babysits for 4 hours making $10.00 an hour for a total of 4 * 10 = $40.00. Over 7 days, she makes 140 + 125 + 40 = $305.00. The answer is 305.
