Let C represent the cost of a coach ticket
Let B represent the cost of a business ticket
Washington: 150C + 50B = 18,450
NY City: 170C + 100B = 27,280
Solve the system using the Elimination method:
-2(150C + 50B = 18,450) → -300C - 100B = -36,900
1(170C + 100B = 27,280) → <u>170C + 100B = 27,280 </u>
-130C = - 9,620
<u> ÷ -130 </u> <u> ÷ -130 </u>
C = 74
x^4 + 7x^3 - 2x^2 - 9x - 3 - (10/x+8)
