Explanation
The total money equation is 12.50s + 14p = 1,225, because each story subscription costs $12.50 and each puzzle subscription costs $14. The statement that the number of story subscriptions is 20 more than twice the number of puzzle subscriptions translates to s = 2p + 20. Together, these equations are choice D.
