3. The Windless Surfing Company has determined its cost for making custom sails to be C = 380 + 18S, where C is the cost in dollars, and S is the number of sails. If the cost can be higher than $4,000 but must be smaller than $11,000, how many sails can they make per week? (You must set up an inequality.) ​
