Take another look at the sentence:

Jim's last temper tantrum __________ $200. He had thrown an expensive titanium three-wood into the golf course lake, and his wife Nancy insisted that he hire a scuba diver to retrieve it.

The sentence requires the past tense of cost, an irregular verb that never changes form. Cost, then, is the simple past form.

Verb Simple Present Simple Past Past Participle
cost cost(s) cost cost

Costed, the form you chose, is a spelling error. Before you continue, review the rules for irregular verbs.
