Question

Abba grew 1 foot over the past year. He is now 5 feet tall. Part B: Use your model in Part A to write and solve a proportion to find the percent increase in Abba's height.

Answer 1

25%

Explanation:

Abba grew 1 foot over the past year. He is now 5 feet tall. What was Abba's percent increase in height?

Step one:

given data

We are told that Abba grew 1 foot in the past year, and now he is 5 feet tall, this means that his previous height is 4 feet.

Step two:

We want to find the percent increase

%increase = change in height/ previous height *100

%increase =5-4/4*100

%increase = 1/41*100

%increase =0.25*100

%increase = 25%
