To find the initial value (the amount at the start, which we can consider as year 0), we can analyze the changes in the amount over the years.
Looking at the amounts given:
- After 1 year: $1,080
- After 2 years: $1,160
- After 3 years: $1,240
From year 1 to year 2, the amount increased by $80 ($1,160 - $1,080).
From year 2 to year 3, the amount also increased by $80 ($1,240 - $1,160).
This indicates a consistent increase of $80 per year. Therefore, we can go backward to find the initial amount:
- At year 0: Amount at year 1 - Increase = $1,080 - $80 = $1,000
Thus, the initial value is:
$1,000
