Answer:
Step-by-step explanation:
Day 1: $2.70 is added to the value of the share.
$43.85 + $2.70 = $46.55
Day 2: $2.70 is added to the value of the share.
$46.55 + $2.70 = $49.25
Day 3: $1.10 is subtracted from the value of the share.
$49.25 - $1.10 = $48.15
Day 4: $1.10 is subtracted from the value of the share.
$48.15 - $1.10 = $47.05
Day 5: $4.45 is subtracted from the value of the share.
$47.05 - $4.45 = $42.60
After 5 days, the value is $42.60, which is choice B.
Hope this helps!
