Answer: $23000
Step-by-step explanation:
The formula for interest will be:
Interest = Principal × Rate × Time
We'll then slot in the values given and this will be:
6900 = Principal × 5% × 6
6900 = Principal × 0.05 × 6
6900 = Principal × 0.3
Principal = 6900/0.3
Principal = 23000
The amount borrowed is $23000
