The price, s, of a mountain bike at speed cycling is $290 less than twice the price, d, of the same bike at downhill racing. the difference in price between the bike at speed cycling and downhill racing is $304. which system of equations can be used to determine the price of the bike at each store?
s - 2d = -290
s - d = -304

2s - d = 290
s - d = -304

2s - 2d = 290
s - d = -304

s - 2d = -290
s - d = 304
