Each member is encouraged to sell @ least 50 reflectors. You sell 17 on Monday and 12 on Tuesday. How many reflectors do you need to sell on Wednesday to meet your goal?
 
x = number of reflectors you need to sell

17 + 12 + x =50 solve for x
Subtract 17 and 12 from the left side to isolate x
What you do to one side of an equation you must do to the other.
x= 50 - 17 - 12
Combine like terms a.k.a. do the math
x=21

You need to sell 21 reflectors to meet the goal of 50
 
So 17+12 reflectors were sold on Mon and Tues, so add them, =29.
50 minus 29 equals 21,
therefore, reflectors needed to be sold is 21 on Wednesday.
