Scheduling Activity Alex and Andrea are planning a surprise welcoming party for their friend Ana tomorrow evening, They made a list of things to do tomorrow, including the time they think each task will take. 1. Clean the kitchen (60 minutes) 2. Clean the backyard (80 minutes) 3. Decorate the backyard (50 minutes) 4. Set the table (30 minutes) 5. Buy the ingredients for the cake, the coffee, and the tea (70 minutes) 6. Make the cake and clean up while it bakes (90 minutes) 7. Decorate the cake (40 minutes) 8. Make the coffee and get water ready for tea (20 minutes) 9. Have cake and drinks in place ready for the surprise party (10 minutes) They also noted that the kitchen must be dean before starting the cake, the coffee should not be started before the cake is baked, and they need to decorate the backyard after it is clean and before they set up the table. Alex and Andrea will work together to have everything ready.
