Marlon Audio Company manufactures cassette tapes. The desired speed of its model SF2000 is 2 inches per second. Any deviation from this value distorts pitch and tempo resulting in poor sound quality. The company sets the quality specification to 2 ±0.25 inches per second because an average customer is likely to complain and return the tape if the speed is off by more than 0.25 inch per second. The cost per return is $36. The repair cost before the tape is shipped, however, is only $3 per tape. Compute L (x) if x is 2.12 inches per second.
