This was not a helpful video because I do not understand how he knows the price of the burritos.

[@Vonco13]

this wasn't helpful. nowhere did it say what the prices were.

[@Elworkergato]

Well he's doing times and it said that the tacos is the same price to enchiladas so you would times three and five then you would times seven tacos to with the same Price as three burritos so you would times seven and three then what he did is add to get his answer at the end
