Short Answer

Expert verified

No. of $10 $$ share is $15$ and number of $12 $$ share is $5$

Step by step solution

Step 1. Given information

Hilda has $210 $$ worth of $10 $$ and $12 $$ stock shares. The numbers of $10 $$ shares are five more than twice the number of $12 $$ shares.

Step 2. Let the no. of 12$Share be x

No. of $10 $$ share is $= 2 x + 5$

Making the equation and solving we get,

$10 (2 x + 5) + 12 x = 210 20 x + 50 + 12 x = 210 32 x + 50 = 210 32 x = 210 - 50 32 x = 160 x = \frac{160}{32} x = 5$

No. of $12 $$ shareis $5$ and $10 $$ share is $2 \times 5 + 5 = 15$
