750 bikes would be sold for $350
Let x represent the number of bikes sold per month and y represent the price.
550 bikes are sold at a price of $250, this can be represented by (550, 250). Also, 750 bikes is sold at a price of $150, hence it is represented by (750, 150)

y = mx + b
m is the slope, b is the y intercept.
Therefore the function is:

350 = (1/2)x - 25
x = 750
Therefore 750 bikes would be sold for $350
