The local grocery store opens at nine. Its parking lot has six rows. Each row can fit seven cars. Each car has four wheels. How many cars can the parking lot fit? And I encourage you to pause the video
and think about this yourself. Try to figure it out on your own. So, let’s re-read this. The local grocery store opens up at nine. Well, that doesn’t really matter. If we’re thinking about
how many cars can the parking lot fit. So we don’t really have to care about that. We also dont have to care about
how many wheels each car has. They’re not asking us how many
wheels can fit in the parking lot. So we can ignore that. What we really care about is
how many rows we have. And how many cars can fit in each row. What we have is — We have six rows
and each row can fit seven cars. We’re going to six groups of seven. Or, another way of thinking about it. We’re going to have six times seven
cars can fit in the parking lot. What is this going to be equal to? This is literally six sevens added up. This is the same thing as
one, two, three, four, five, six. That last seven looks strange. Now we’re going to add these up. Seven plus seven is fourteen. Twenty-one, twenty-eight,
thirty-five, forty-two. Six times seven is equal to forty-two. So forty-two cars can fit in the parking lot.
Don’t believe me? I made a little diagram here. We have six rows. This is the first row. Second.. Third.. Fourth.. Fifth.. Sixth. Each row can fit seven cars.
You see it here. One; Let me make that a little brighter. One.. Two.. Three.. Four, five, six, seven. How many cars are there? You have seven. Fourteen.. Twenty-one.. Twenty-eight.. Thirty-five.. Forty-two total cars. Six rows of seven.
