Question

When Hugo was 9 years old he was 56 inches tall. Hugo is now 12 years old and he is 62 inches tall. Find the percent of increase in Hugo’s height to the nearest tenth.

Answer 1

increase%=10.7%

Explanation:

Percentages

The initial height of Hugo was 56 inches, and his new height is 62 inches. This means he increased his height by 62 - 56 = 6 inches.

Now we find the percent of increase. Assuming the initial height as a reference, the change in height will be compared to the initial height as follows:

`\displaystyle increase\ \%=(6)/(56)*100\%`

increase%=10.7%
