Answer 1

@texaschic101 I think its D. am I correct ?

Answer 2

6c + 3t = 4800
8c + t = 4600 --->(-3)
-------------
6c + 3t = 4800
-24c - 3t = - 13,800 (result of multiplying by -3)
--------------add
- 18c = - 9000
c = 500

6c + 3t = 4800
6(500) + 3t = 4800
3000 + 3t = 4800
3t = 4800 - 3000
3t = 1800
t = 600

6c + 3t = 4800
6(500) + 3(600) = 4800
3000 + 1800 = 4800
4800 = 4800 (correct)

2c + 3t =
2(500) + 3(600) =
1000 + 1800 = 2800 <=== the answer I am getting is C
