Answer:
The percentage change if I increase $3.00 to $ 4.50 is 50%
Solution:
We have to find the percentage change when I increase $3.00 to $4.50
To calculate the percentage change we use the below given formula
[tex]\text { Percentage change }=\frac{\text {Final value-Initial value}}{\text {Initial value}} \times 100[/tex]
Here $ 3.00 is increased to $4.50.
Hence the initial value is $ 3.00 and the final value is $4.50.
Substituting the initial and final values in the formula we get,
[tex]\text { Percentage change }=\frac{4.50-3.00}{3.00} \times 100 \%[/tex]
[tex]=\frac{1.50}{3.00} \times 100 \%[/tex]
[tex]=\frac{1}{2} \times 100 \%[/tex]
= 50%
Therefore the percentage change from $3.00 to $4.50 is 50%
