In 2014, the number of tourists who visited Malaysia was 25.6 million. In 2015, the number of tourists increased by 4%. In 2016, there were 30 million tourists. What was the increase in percentage in 2016 compared to 2015?
SOLUTION:
The number of tourists in 2015:
\(\space\space\space\space25.6\text{ million}+4\%\times25.6\ \text{ million}\\=25.6\text{ million}+\dfrac{4}{100}\times25.6\text{ million}\\ =25.6\text{ million}+1.024\text{ million}\\ =26.624\text{ million}\)
The increase in the number of tourists in 2016:
\(30\ \text{million}26.624\text{ million}=3.376\text{ million}\)
The increase in percentage:
\(\dfrac{3.376}{26.624}\times100\%=12.68\%\)
