The rule at Anna's house is that if she eats all of her vegetables and does all of her chores each day, she earns 2 hours of int
ernet time which she can save. Anna started her week with 3 hours saved. If she eats all of her vegetables and does all of her chores each day for 4 days straight, how many hours does she have after the 4 days if she uses 6 hours of her internet time?
She started with 3 hours saved and got 2 more hours for each day that she did her chores and ate her vegetables. Since she did her chores and ate her vegetables 4 days that means that in total she gained 8 hours (4 * 2) plus the ones she already had saved. So 8 + 3 = 12 - 6 = 6
