The monthly sales at an import store are currently $10,000 but are expected to be declining at the rate of S'(t) = -10t^(2/5) dollars per month t months from now. The store is profitable as long as the sales level is above $8,000 per month. Find a formula for the expected sales in t months. (5pts) (-50/7)t^(7/5) + 10,000 + c (-50/7)t^(7/5) + 10,000 (-50/7)t^(7/5) + c (-50/7)t^(7/5) 7) What sales figure should be expected 2 years from now? (5pts) $10,018.85 + c $9,388.82 + c $10,018.85 $9,388.82
