John's neighbor tells him to walk his dog for 1 hour each day for a total of $10. He does this for April, save for the 4 Sundays in April. He later spent $50 on books and gave his sister Kaylee the same amount. How much money did John have left?
April has 30 days, so if he didn't walk the dog on Sundays, he worked for a total of 30 days - 4 days = <<30-4=26>>26 days.
If each day he earned $10, he ends up with 26 days * $10/day = $<<26*10=260>>260 .
After buying books and giving his sister $50, he ends up with $260 - $50 - $50 = $<<260-50-50=160>>160
