Question

Last year, Maria had 3 dogs and Tessa had 5 Dogs. This year, Maria has 6 dogs and Tessa has 2 dogs. What is the difference between the percent increase in dogs for Maria, and the percent decrease in dogs for Tessa?

Answer 1

Maria: 100%

tessa: -60%

Explanation:

maria: (6- 3) : 3 = 1

1 x 100 = 100%

tessa: ( 2 - 5) : 5 = -0.60

-0.60 x 100 = -60 %

Answer 2

Explanation:

Maria:

Increase = 6 - 3 = 3

Percentage of increase =
`(3)/(3)*100` = 100% increase

Tessa:

Decrease= 5 - 2 = 3

Percentage of decrease =
`(3)/(5)*100` = 3 * 20 = 60%

Difference = (100 - 60)% = 40%
