FR EE POINTS BUT IF YOU CAN GUESS WHAT YEAR I WAS BORN YOU"LL GET BRIANLIEST.

Darius sold 50 milkshakes while working at Cool Treats. 40% of the milkshakes were vanilla. The rest were chocolate. After Darius sold some more vanilla milkshakes, the percentage of chocolate milkshakes decreased to 5%. How many more vanilla milkshakes did Darius sell?

decreased to and decreased by have a different meaning

...the percentage of chocolate milkshakes decreased to 5% (from 60%)

So, Darius sold 95% vanilla milkshakes and 5% chocolate milkshakes.

5% / 30 = 95% / x            x = 570

Darius sold 550 more vanilla milkshakes.

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
