Kevin and Kara are in a pancake-eating contest. Kevin can eat three pancakes per minute, while Kara can eat $3360_w20_h37.png$ pancakes per minute. How many total pancakes can they eat in 10 minutes?
If Kevin eats 3 pancakes in one minute, you know he eats 3(10) = 30 in 10 minutes. If Kara eats $3360_w20_h37.png$ per minute, she eats 3.5 × 10 = 35 in 10 minutes. Add 30 + 35 = 65 and you have your answer.
