a bus company currently has a daily ridership of 4000 passengers at a price of $2 a ticket. The company must have daily revenues of $10450. For every $0.15 increase they will lose 40 passengers. What fare should they charge?
I think that the equation is... but I'm not sure
10450=(4000-40x)(2+015x)
the other question is
a soccer field, 110m x 60m is to be surrounded by an area of equal width for spectators. If the area of the field and spectator area is to be 9374 square metres, how wide is the spectator area?
