3. If Alex puts the cake in at 2:20 pm and sets a timer for 55 minutes, the timer will go off at 3:15 pm. Think if it like this, 2:20 pm + 1 hour (60 minutes) is 3:20 pm. Then just subtract five minutes, making it 3:15 pm.
4. If 4 cups are in 1 quart, then 8 cups are in 2 quarts. HOWEVER, the question is asking for how many 1/2 cups in 2 quarts. Basically, there are 16 one half cup servings in 2 quarts.
5. a) If you need 3 eggs per person to make an omelet, you could make an omelet for 4 people with a dozen eggs, as there are 12 eggs in a dozen and 3x4 is 12.
b) Each person will 2 pieces of bacon if the slices are split up fairly, because there are a total of 4 people and 8 pieces of bacon. (8 divided by 4 is 2).
I hope this helps with the first few questions!
