Astadium has 47,000 seats. seats sell for $28 in section a, $24 in section b, and $20 in section c. the number of seats in section a equals the total number of seats in sections b and c. suppose the stadium takes in $1,187,200 from each sold-out event. how many seats does each section hold?

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
