Answer with Step-by-step explanation:

Bob worked 15 consecutive day, earning an average wage of $90 per day.

Total wage for 15 days= $(90×15)

                                    = $1350

During the first 7 days his average was $87/day

Total wage for first 7 days=$(87×7)

                                  = $609

During the last 7 days was $92/day.

Total wage for last 7 days= $(92×7)

                                         = $644

Total wage for 15 days=Total wage of first 15 days+ Total wage of 8th day+ Total wage for last 7 days

⇒ 1350 = 609+wage of 8th day+ 644                  

⇒ wage of 8th day=1350-609-644

⇒ wage of 8th day=$97

Hence, Correct option is:
