Anna, Laura and David each earn the same monthly salary each month Anna saves 19% of her salary and spends the rest of it Laura saves 17/20 and spends the rest amount of salary David saves : amount of salary he spends 2:8 who saves the most of their salary?

david would saved 20%

Step-by-step explanation:

The computation is shown below:

Given that

Anna saves 19%.

Laura spends 17 by 20 i.e.  85 by 100 so it saves  15%.

The ratio of david salary saved to spend be 2:8

20% : 80%

So david would saved 20%

This represent that most of the salary would spend by david

The same is relevant too

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
