Skateboard revenue: a skateboard shop sells about 50 skateboards per week for the price advertised. for each $1 decrease in price, about 1 more skateboard per week is sold. the shop's revenue can be modeled by y=(70-x) (50+x). use vertex form to find how the shop can maximize weekly revenue.
[i can get this into vertex form, but i'm not understanding how to read the vertex form of the equation to answer the question]

gives the maximum (if a<0) at coordinates 
, where 
. If a>0, the same formula gives the minimum (there's no maximum)
