As per given by the question,
There are given that the price of unleaded gas was $2.84yesterday and today price is $2.89.
Now,
The yesterday price is $2.84, and today price is $2.89.
So,
The increases price is,
[tex]2.89-2.84=0.05[/tex]Then,
The percentage of the increases price is;
[tex]\begin{gathered} \frac{2.89-2.84}{2.84}\times100 \\ \end{gathered}[/tex]Then,
[tex]\begin{gathered} \frac{2.89-2.84}{2.84}\times100=\frac{0.05}{2.84}\times100 \\ =1.76 \\ \approx1.8 \end{gathered}[/tex]Hence, the percentage increases price is 1.8%
