Anit [1.1K]

$\text{Answer : Number of \$45 shares} =120$

$\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355$

Explanation:

Let number of $ 25 shares be 3x-25

According to question,

$x+3x-5=475\\\\4x-5=475\\\\4x=475+5\\\\4x=480\\\\x=\frac{480}{4}\\\\x=120$

So,

$\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355$
