[tex]\bold{\underline{ Let's \: Begin :- }}[/tex]
According to the question,
Cost of 1 share of ABC company = $18.75
Therefore,
Cost of 140 shares purchased by Jan in the ABC company
[tex]\sf{ = 140 × 18.75 }[/tex]
[tex]\sf{ = 2625\: dollars }[/tex]
Now,
For next 3 days, the value of share declined
[tex]\sf{ = (1 + 1.75 + 1.50)dollars }[/tex]
[tex]\sf{ = 4.25 \: dollars }[/tex]
Therefore,
The value of shares after 3 days will be
[tex]\bold{ = }{\bold{\frac{2625 - 4.25}{ 140}}}[/tex]
[tex]\bold{ = }{\bold{\frac{ 2620.75}{ 140}}}[/tex]
[tex]\bold{\red{ = 18.75\: dollars}}[/tex]
Hence, The value of share after 3 days will be $18.75 .
