Question: Vivian plays 10 Spotify songs every day. Her best friend Clara plays 2 fewer songs each day. If in June they didn't play any song during the weekends only, and there were 8 weekend days in June, what's the total number of songs they both listened to in that month?
Answer with step-by-step thinking: June has 30 days, so if they didn't play any songs on weekends, then they played 30 days - 8 days = 22 days. If Vivian played 10 songs each day, the total number of songs she played for the month is 10 songs / day * 22 days = 220 songs. Clara played 2 fewer songs, which is 10 songs / day - 2 songs / day = 8 songs / day. The total number of songs played by Clara for the whole month is 8 songs / day * 22 days = 176 songs. The total played by both is 220 songs + 176 songs = 396 songs.
So the answer is 396.


Question: Hawkeye is driving to his aunt. He has to charge his battery for $3.5 per charge. If he charged his battery four times, and his battery charging budget was $20, how much money was he left with when he reached his aunt's place?
Answer with step-by-step thinking: If each battery charge costs $3.5, the total expense of 4 battery charges is 4 * 3.5 = $14. After his expense on battery charging, his balance was 20 - 14 = $6.
So the answer is 6.
