The school wants to buy a new speaker system for the football stadium with the money they raised from the bake sale. They compared speaker system prices from two different distributors.

From Schools'R'Us, a system, t, costs $280 less than three times the price of the same speaker system, d, at The Warehouse. The difference in price between the speaker system at Schools'R'Us and The Warehouse is $288.

What system of equations can be used to determine the price of the speaker system at each distributor?
