Percent of turn pike is 75% and percent of parkway is 25%.
Solution:
Given, The state of New Jersey makes approximately $1.55 billion annually from tolls of the $1.55 billion
About [tex]\frac{3}{4}[/tex] comes from tolls on the turnpike
Remaining [tex]\frac{1}{4}[/tex] comes from tolls on the parkway
To find the percent of the total revenue from turnpike:
[tex]\begin{array}{l}{\text { Percent of turnpike }=\frac{\text { amount from parkway }}{\text { total revenue }} \times 100} \\\\ {=\frac{\frac{3}{4} \text { of total revenue }}{\text { tot al revenue }} \times 100} \\\\ {=\frac{\frac{3}{4} \times \text { total revenue }}{\text { total revenue }} \times 100} \\\\ {=\frac{3}{4} \times 100=3 \times 25=75 \%}\end{array}[/tex]
To find the percent of the total revenue from parkway:
[tex]\begin{array}{l}{\text { Percent of parkway }=\frac{\text { amount from parkway }}{\text { total revenue }} \times 100} \\\\ {=\frac{\frac{1}{4} \text { of total revenue }}{\text { total revenue }} \times 100} \\\\ {=\frac{\frac{1}{4} \times \text { total revenue}}{\text { total revenue }} \times 100} \\\\ {=\frac{1}{4} \times 100=25 \%}\end{array}[/tex]
Summarizing the results:
Percent of turn pike is 75%
Percent of parkway is 25%
