Answer:
- decrease: $1881
- ending value: $4719
Explanation:
The decrease is found by multiplying the original amount by the percentage decrease:
$6600 × 28.5% = $6600 × 0.285 = $1881
Jose's account decreased by $1881.
__
The remaining value is the original amount, less the amount of decrease.
$6600 -1881 = $4719
At the end of last year, Jose had $4719 in his investment account.
