The water is being turned off and so Matthew is filling up his bathtubs with water as a reserve. If he has 17 bathtubs, and each can store 10 liters of water, choose the equation that will tell us how much water there is. \(?\)

\(17 \, \times \, 10 \, = \, x\)

\(17 \, \times \, x \, = \, 10\)

There are 15 soda pops in the fridge. If Brianna goes shopping and buys 12 more soda pops, which equation will tell us the total number of soda pops? \(?\)
