At the movie theatre, child admission is $6.00 and adult admission is $9.60. On Saturday, 135 tickets were sold for a total sales of $1087.20. How many child tickets were sold that day?

58 child tickets were sold

Step-by-step explanation:

If 58 child tickets were sold, then that would mean that 77 adult tickets were sold because they need to add up to 135 total tickets sold.

We can multiply 58 by $6 to get the total sales for just the child tickets which will give us $348.

Next, we can multiply 77 by $9.60 to get the total sales for the adult tickets which will give us $730.20

Then when we have both of our sales for the children tickets and the adult tickets, we can add them together to get a total amount of sales of $1087.20

(sorry if this is confusing but I hope this helped!)

2nd one in the first row is correct

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
