Toll Booth You lose your electronic tag that you use to pay tolls on the highway in your city. It costs you $24 to replace the tag. The cost of one toll when you don’t use the tag is $3. The cost of the same toll when you do use the tag is $1.50. How many times will you have to use the tag to pay for the tolls in order for the total cost to be same as not using the tag?
I will have to use the tag 16 times.
The cost of replacing a tag = $24
The cost of one toll without the use of tag = $3
The cost of one toll with the use of tag = $1.50
We have to find the number of times the tag can be used to pay the tolls.
Let the number of tolls = x.
The cost of x times of toll without the use of tag = 3x
The cost of x times of toll with the use of tag = 1.5x
Hence, the equation is,
So, I will have to use the tag 16 times.
