Answer:
The credit card decrease percentage is 71%
Step-by-step 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
= x
71% = X
that is, the decrease in the account when you have $426 available quota is 71%.
