Answer:
C
Step-by-step explanation:
I don't know for sure, but I am pretty sure this is it.
76 is 80% of 95 and I'll even explain.
80/100 = 76/x from this point you cross multiply which gives you 80x = 76(100) you multiply 76 by 100 and get 7600 so then the equation look like this 80x = 7600 then divide by 80 on both sides and get the answer of x = 95 which is basically your answer I hope this helps :)
(6/5.55) * 100 = 108.11 %
The percent error is 108.11 %
72, 96, 84, 12
72 + (7x+24) = 180
7x + 96 = 180
7x = 84
x = 12
