Answer:
2nd one
Step-by-step explanation:
Answer:
2/3 can't be divided because it's in its lowest form so you can reduce it
30 of the $3 tickets were sold
70 of the $2 tickets were sold.
(3*30) + (2*70) = 230
D(t) = -4t^3 + 40t^2 + 500t = 4088
4t^3 - 40t^2 - 500t + 4088 = 0
t = 7
Therefore, the plane has flown 4088 km 7 hours after it took off.
I'm sorry the picture is blurry. Could you post another one.
