The total cost of producing item X is equal to the sum of item X's fixed cost and variable cost. If the variable cost of producing X decreased by 5% in January, by what percent did the total cost of producing item X change in January?
(1) The fixed cost of producing item X increased by 13% in January.
(2) Before the changes in January, the fixed cost of producing item X was 5 times the variable cost of producing item X.

T = F + V
(1)
In Jan
T = 1,13F + 0,95V
How F and V correclate?
inSUFF
(2)
Before Jan
F = 5V, so before Jan T = 6V but what after Jan - how F changed?
inSUFF
(1)(2)
6V / 1,13*5V+0,95V = 6V / 6,6V
