\($12\) for a total of \(20\) mins call
\(X\) for the first \(3\) mins and for the next \(17\) mins, \($0.5/\)minute
\(12 = X + 17 * 0.5\)
\(x = 3.5\)
Answer \(D\)

Given that A telephone company charges X dollars for the first 3 minutes of a call and 50 cents for each additional minute, or fraction thereof. And If a 20 minute phone call costs $12.00, we need to find X
20 mins = 3 mins + 17 mins
=> Charge will be $X (for first 3 mins) + $0.5 * 17 (for 17 additional mins)
= $X + $8.5 = $12 (given)
=> X = $12 - $8.5 = $3.5
So, Answer will be D
Hope it helps!
