Answer: The correct answer is indeed (D. W=d- 1.25)
Step-by-step explanation: sense it wants us to figure out the relationships in the table we first have to find the sum of all the pairs in the table
15.75 - 14.50 = 1.25
9.50 - 8.25 = 1.25
5.25 - 4.00 = 1.25
30.00 - 28.75 = 1.25
being all the pairs add upto the same number "1.25" which tells us she spent exactly 1.25$ everyday getting to work
so by getting that the relationship in the table (D. W=D-1.25).
because everyday at the beginning she only spends 1.25$ going to work so d. represents the money before she spends w. represents the money after she spent and only 1.25$ is being subtracted from the starting amount.
Therefore your answer would be W = D -1.25$
