Answer:
C. a two-day ticket
Step-by-step explanation:
According to the given situation the two-day ticket is wrong as of value because the amount that determined in ultility would be equivalent to the $120
The value in one day is
= $120 - $115
= $5
And,
= $120 + $50
= $170
On second day
= $170 - $150
= $20
And,
= $170 + $15
= $185
On third day
= $185 - 170
= $15
So based on this the two ticket should be chosen
