Darleen gets $10 a week allowance. She walks her neighbor's dog 6 days each week and earns $3 each day. She earns $7 an hour doing odd jobs. Darleen wants to save $15 a week, give $5 a week to charity, and have at least $20 each week to spend. How many hours of odd jobs does she need to each week to earn enough money?
