Answer 1

Less than 25%

Explanation:

1189 divided by 967 is 1.229576008...

1.229576008... multiplied by 967 is 1189

This number, 1.229576008..., is a multiplier

To be exact it increases by 22.9576008...%

That is less than 25%

Answer 2

Given:

This week= 967 people

Last week= 1189 people

To find:

The percentage decrease.

Solution:

`\% \: decrease = - 100 * ((final - initial))/(initial)`

`\% \: decrease = - 100 * ((967 - 1189))/(1189)`

`\% \: decrease = - 100 * ( - 222)/(1189)`

`\% \: decrease = 18.67115223 \: \%`

`\% \: decrease = 18.7 \: \%`

So it's less than 25%
