In many cities, discount clubs are popular. For a fixed annual fee (paid in advance) one can purchase goods at 90% of their listed price (in other words, 10% off the list price); otherwise, one pays the list price. Suppose that the annual fee is $200 and the interest rate on your savings account is 1%. Finally, assume discount club's list prices are the same as any other store.

If the Ho family plans to spendat least___ dollars at the store, they should join the discount club.
