Answer 1

Answer:

David, 20%

Step-by-step explanation:

Anna saves 19%.

Laura spends 17/20 , or, 85/100=> Laura saves 15/100; 15%.

amount of salary David saves : amount of salary he spends = 2:8,

or, 20/100 : 80/100

=> David saves 20/100;  20%.

David saves the most, (20%).

Answer 2

David saves more money than Laura and Anna and this can be determined by using the given data and converting that data into percentages.

Given :

• Anna, Laura, and David each earn the same monthly salary.
• Anna saves 19% of her salary and spends the rest of it.
• Laura spends 17/20 of her salary and saves the rest of it.
• Amount of salary David saves : amount of salary he spends = 2:8

Let the total amount of money Anna, Laura, and David each earn be 'x'.

Now, according to the given data Anna saves 19% of her salary and spends the rest of it. So, the amount of money Anna saved is:

= 19%

It is also given that Laura spends 17/20 of her salary and saves the rest of it. So, the amount of money Laura saved is:

$=\dfrac{3}{20}$

= 15%

It is given that amount of salary David saves : amount of salary he spends = 2:8. So, it can be written as 20/100:80/100. So, the amount of money David saved is:

= 20%

David saves more money than Laura and Anna.
