Answer

Explanation:

Step1: Identify old and new values

Old value (July 2020) = $1100$, New value (July 2021) = $1300$.

Step2: Use percent - increase formula

Percent increase=$\frac{\text{New value}-\text{Old value}}{\text{Old value}}\times100%=\frac{1300 - 1100}{1100}\times100%$.

Step3: Calculate the difference

$1300−1100 = 200$.

Step4: Calculate the fraction

$\frac{200}{1100}\approx0.1818$.

Step5: Convert to percentage

$0.1818\times100% = 18.18%\approx18.2%$.

Answer:

18.2%
