Question

In 2010, the number of clown costumes sold at a single costume shop was 17. By 2015, that number had grown to 39. Assuming a constant increase in clown costume sales, calculate the unit rate of change (slope) from 2010 to 2015.

Answer 1

Answer:

No of clown sold in 2010 = 17

No of clown sold in 2015 = 39

Unit rate of change = 39 - 17/17 x 100

Unit rate of change = 129.41%

Explanation

The unit rate of change from 2010 to 2015 is equal to the number of clown sold in 2015 minus the number of clown sold in 2010 divided by the number of clown sold in 2010 multiplied by 100.
