8 foot long wooden pole costs $3.00

=> 8 foot long wooden pole costs 300 cents

=> 8 * 12 = 96 inches long wooden pole costs 300 cents

=> 1 inch long wooden pole costs \(\frac{300}{96}\) cents

=> 16 inches long wooden pole costs \(16 * \frac{300}{96}\) = 50 cents

Hence option C

1 foot equal to 12 inches

8 foot equal to (8*12) = 96 inches.

Now,

96 inches pool costs 300 cents

1 inches pool costs 300/96

16 inches pool costs (300/96)*16


= 50 cents

The best answer is C.

1 $ = 100 Cents
1 Foot = 12 Inches

Let, X = Cost, in cents, of pole that is 16 inch long

Therefore,
Rate1 = Rate2
8 Foot / 3 $ = 16 Inch / X
8 * 12 Inches / 3 * 100 Cents = 16 Inch / X
X = 50 Cents

Hence, C.
