Answer:2
The second one because it is 108in and the first one is 47.6
If they were equal both times they checked this means that 15% of their $ was equal to $210
so 15/100 = 210/x
so .15x=210
x=210/.15
x = 1400
x=1 f = 10(5.5)(1) = 55
x=2, f = 10(5.5)(2) = 110
110-55 = 55
2-1 =1
55/1 = 55
average rate of change = 55
5
The reason is because |-5| is equal to 5. The absolute value bars make the number positive.
Since the number is less that 1, the exponent will be a negative.
