Answer:
its debt decreased by 16.6%
Step-by-step explanation:
If you decreased your debt from $ 90 to $ 75, it means that the rebate was $ 15
In percentage terms, you can calculate debt abatement in two ways:
Let x denote the value
1) By rule of 3
90 ---- 100%
15 = x%
x = 1500/90
x = 16.6%
2) Divide the discounted value by the total value
15/90 = 0.166
Then, simply multiply by 100 to reach the percentage
0.166 x 100 = 16.6
Therefore, its debt decreased by 16.6%
