The partnership agreement includes the following provisions regarding the division of net income: interest of 10% on original investments, salary allowances of $36,000(Schmidt) and $22,000(Cohen), and the remainder equally.
After adjustments and the closing revenue and expense accounts at May 31,2010, the end of the first full year of operations, the income summary account has a credit balance of $84,000, and the drawing accounts have debit balances of $30,000(Schmidt) and $25,000(Cohen).
How do I journalize the entries to close the income summary account and the drawing accounts at May 31,2010?

This should be back in about chapter 4 or so of your book.

It's all about reversing a balance out and moving it elsewhere. A credit balance in Income Summary gets debited to get rid of it. That credits into the capital account(s).

The drawing accounts are debits, so they have to be credited to get rid of their balances. And that debits into the capital account(s).

Net income increases capital, so it's reasonable that should be credited into capital. (That's why revenues are credits to begin with.) And drawings decrease capital, so it's also reasonable that should be debited out of capital. (Again, that's why drawing is a debit.)
