Answer:
1st- 4, 2nd- 9, 3rd- 14, 4th- 19, 5th- 24, 6th- 29, 7th- 34, 8th- 39, 9th- 44, 10th- 49, 11th- 54, 12th-59
Step-by-step explanation:
1st- 4
2nd- 4+15-10= 9
3rd- 9+15-10=14
4th- 14+15-10=19
5th- 19+15-10=24
6th- 24+15-10=29
7th- 29+15-10=34
8th- 34+15-10=39
9th- 39+15-10=44
10th- 44+15-10=49
11th- 49+15-10=54
12th-54+15-10=59
Answer: The Answers are A, and C.
Answer: the first one is $0.35

Note: Since the symbols for greatest integer function (GIF) and least integer function (LIF) are not given, I will be using the words GIF and LIF in the solution
GIF x means largest integer less than or equal to x, and LIF x means least integer greater than or equal to x.
We need to determine which expressions are equal
Option 1: GIF 4.9 and LIF 3.1
GIF 4.9 = 3
LIF 3.1 = 4
Hence GIF 4.9 ≠ LIF 3.1
Option 2: GIF 15.2 and GIF 14.8
GIF 15.2 = 15
GIF 14.8 = 14
Hence, GIF 15.2 ≠ GIF 14.8
Option 3: GIF -6 and LIF -6
GIF -6 = -6
LIF -6 = -6
Hence, GIF -6 = LIF -6
Option 4: LIF -3.2 and LIF -2.6
LIF -3.2 = -2
LIF -2.6 = -1
Hence, LIF -3.2 ≠ LIF -2.6
Hence, only in Option C the pair of expressions are equal.
