Explanation:

To know the percentage of decrease of the card we will make a simple rule of three, which indicates the value we need.

We have that 100% of the card quota is 600, and we want to know how much the percentage decreases when the account has 426 available, we do the following;

100% ---> $600

X -----> $426

100 * 426 = x * 600

\frac{100 * 426}{600} = x

71% = X

that is, the decrease in the account when you have $426 available quota is 71%.

Lots of debt incorporation= equity/multiplier

= 34.25/2.00

= 17.13%

Lots of equity incorporation= equity/multiplier
