Use the strategy for solving word problems, modeling the verbal conditions of the problem with a linear inequality. The toll to a bridge is $3.00. A three-month pass costs $7.50 and reduces the toll to $0.50. A six-month pass costs $30 and permits crossing the bridge for no additional fee. How many crossings per three-month period does it take for the three-month pass to be the best deal?

Let's note: x=the number of crossing per three-month period
We write the inequality which models the problem: 7.50+0.50x<302
We solve the inequality: 7.50+0.50x<15
7.50+0.50x7.50<157.50
0.50x<7.50
x<7.500.50
x<15
