Antonio would like to replace his golf clubs with a$$ custom$-$measured set. A local sporting goods megastore is advertising custom clubs for $$$$870,$ including a new bag.$$ In$-$store financing is available at $4\mathrm{.}77$percent$,$ or he can choose not to renew his $$$$600$ certificate of deposit$($CD$),$ which just matured. The advertised CD renewal rate is $6\mathrm{.}46$ percent. Antonio knows the$$ in$-$store financing costs would not affect his$$ taxes, but he knows$$ he'll pay taxes $(25$ percent federal and $5\mathrm{.}75$ percent$$ state$)$ on the CD interest earnings.
