Answer:
700%
Step-by-step explanation:
The price increased from $0.30 to $2.40. What is the rate of increase, in percentage?
We can use the formula shown below:
[tex]\frac{New-Old}{Old}*100[/tex]
Where
New Price is 2.40 and the Old Price is 0.30
We substitute and calculate:
[tex]\frac{New-Old}{Old}*100\\\frac{2.40-0.30}{0.30}*100\\=7*100\\=700[/tex]
Hence,
Price increased 700%
