hey you have less than a minute and a half. that takes much too long. subtract the two equations
that arranges to
A= 3.50 +C
so 2( 3.50 +c) + 6 c =67.0 by plugging into to second equation
8c = 60
c = 7.50
plug into the one known
6* 7.50 + 2 A = 67
2A = 67-45
2A = 22 A = 11
almost there

so ( in your head)
1A + 2 C = total
11 + 2 ( 7.50) = 26.00
