Answer:
100 + 0.8 ( x - 100 ) = 250
Step-by-step explanation:
We know that a department store gives 20 % off the portion of the bill that is over 100 dollars.
Total bill is 250 and x is the amount of money she would have spent without the promotion.
The cost to which the discount applies is 0.8 ( x - 100 ).
Finally: 100 + 0.8 (x - 100) = 250.
