Short Answer

Expert verified

No. of $45 $$ share is $5$ and number of sharesis $10$

Step by step solution

Step 1. Given information

Mario invested $$ 475$ in $$ 45$ and $$ 25$ stock shares. The number of $25 $$ shares was five less than three times the number of $45 $$ shares.

Step 2. let the no. of $45 share is x

No. of $25 $$ share is $= 3 x - 5$ $$ 25$

Step 3. Making and solving the equation

$25 (3 x - 5) + 45 x = 475 75 x - 125 + 45 x = 475 120 x - 125 = 475 120 x = 475 + 125 120 x = 600 x = 5$

No. of $45 $$ share is $5$ and $25 $$ share is $3 (5) - 5 = 10$
