how many sails can they make per week?

Question

The 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 must be higher than $3998 but must be smaller than $11,000, how many sails can they make per week?

Answer 1

Solve this inequality for S.

 

3998 < 380 + 18S < 11000

 

 

The value of S that is obtained will be a range of values.  That means that the number of sails produced falls under a certain range.
