The answer is $94.40 because he paid 9.44 in sales tax and you need to multiply that by 10 since sales tax is 10%. So, you will get a result of $94.40. You could also check this by multiplying 94.40 by 0.10 and if you get 9.44 (which you do) then it is correct.
It is c 8 II hope I helped
Answer : -3.3b + 3.5x - 84.82
(-14.2b - 97.35) + (10.9b + 12.53 + 3.5x)
= (-14.2b + 10.9b) + (3.5x) + (-97.35+12.53) ||| COMBINE LIKE TERMS
= -3.3b + 3.5x - 84.82
