Answer to Problem 27E
Total number times the tag can be used to pay the tolls is 16 times.
Explanation of Solution
Given information: data provided in the question,
Cost of replacing a tag is $24
Cost of one toll without the use of tag is $3
Cost of one toll with the use of tag is $1.50
Calculation:
Assume the number of tolls to be x.
Therefore,
Cost of xtimes of toll without the use of tag is 3x
Cost of xtimes of toll with the use of tag is 1.5x
Therefore, the equation can be written as,
The equation is solved as,
Hence, 16 times the tag can be used to pay the tolls
