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?
Augustus and Luna can make a total of 3 + 7 = <T>add(3, 7)=10 milkshakes per hour.
Therefore, they made a total of 10 x 8 = <T>multiply(10, 8)=80 milkshakes in 8 hours.
