Augustus can make 3 milkshakes per hour while Luna can make 7 milkshakes per hour. If Augustus and Luna have been making milkshakes for 8 hours now, how many milkshakes have they made?
Thoughts? Step-by-step reasoning:
Augustus and Luna can make a total of 3 + 7 = 10 milkshakes per hour. Therefore, they made a total of 10 x 8 = 80 milkshakes in 8 hours.
Thus, the answer is 80.
