T = 5 + C

1,925 = 150*T + 85*C
1,925 = 150 (5+C) + 85C

1,925 = 750 + 150C + 85C

1,175 = 235C

C = 5
T = 5 + C = 5+5 = 10

T + C = 15

Another approach would be to pick from the numbers, normally I would pick C to know if I need to move to A and B or D and E

If we pick T + C = 15
We know T = C + 5
So 2C + 5 = 15
C = 5
5*85 = 425
And 10 *150 = 1,500

1,500 + 425 = 1,925.

5 more tables than chairs --> T - C = 5, T = c + 5

given 150T + 85C = 1925
150(C+5) + 85C = 1925
C = 5
so T = 10
total =15
