Question 1188003
i believe it's selection 4 (2d - 150)


on tuesday, d dollars worth of merchandise was sold.
on wednesday, 150 less than twice the amount of merchandise sold on tuesday was sold.


that appears to be 2d - 150.
2d means twice the amount of dollars sold on tueday.
2d - 150 means 150 less than twice the amount of dollars sold on tuesday.


solution:


y = 2d - 150
y represents the amount sold on wednesday.
d represents the amount sold on tuesday.


as an example:
assume 500 was sold on tuesday.
y = 2d - 150 becomes:
y = 2 * 500 - 150 = 1000 - 150 = 850.


500 was sold on tuesday,
850 was sold on wednesday.
2 * 500 = 1000 - 150 = 850.


example confirms the formula is good.


2d - 150 is your solution.
