For this problem, we are told that a group of friends have $30, but they need more money for the tickets and uber. We need to calculate how much they need based on the percentages.
The base value is $30, they need 14.3% more for the ticket and 2.9% more for the uber. So we have:
[tex]\begin{gathered} \text{ uber}=\frac{2.9}{100}\cdot30=0.87\\ \\ \text{ ticket}=\frac{14.3}{100}\cdot30=4.29 \end{gathered}[/tex]They need $4.29 more for the ticket and $0.87 more for the Uber.
