<PRE><B>Question 178480</B>
The subway fare in a city is $1.55.
 People eho use the subway may buy a monthly coupon book for $12.00. 
The coupon book reduces the fare to $0.95. 
Determine the number of fares in one month the subway must be used such that the total monthly cost without the coupon books is equal to the total monthly cost with the coupon book. 
--------------------------------
Equation:
total without the coupon books is equal to the total with the coupon book
1.55x = 12.00 + 0.95x
0.60x = 12
x = 20 (# of fares for which each plan results in equal cost)
====================
