Tickets at a play cost $10 or $14. If 800 tickets were sold and $9,040 was collected by the box office, how many $14 tickets wer
pav-90 [236]
STEP 1:
determine equations needed

x= # of $10 tickets
y= # of $14 tickets

QUANTITY EQUATION
x + y= 800

COST EQUATION
$10x + $14y= $9,040


STEP 2:
multiply quantity equation by -14

-14(x + y)= -14(800)
-14x - 14y= -11,200


STEP 3:
add new quantity equation in step 2 to cost equation of step 1 to solve for x using elimination

-14x - 14y= -11,200
10x + 14y= 9040
y term cancels out

-4x= -2160
divide both sides by -4

x= 540 ten dollar tickets


STEP 4:
substitute x value in step 3 into either original equation

x + y= 800
540 + y= 800
subtract 540 from both sides

y= 260 fourteen dollar tickets


ANSWER: There were 540 $10 tickets and 260 $14 tickets sold.

Hope this helps! :)

Segment AB with endpoints at A(2, 4) and B(2, 18) is partitioned by point P according to the ratio of 3:4. Find the coordinate o
natta225 [31]

Using proportions, it is found that the coordinates of point P are given as follows: (2,10).

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The segment is partitioned by point P according to the ratio of 3:4, hence:

P - A = \frac{3}{7}(B - A)

This proportion is applied for both coordinates, hence, for the x-coordinate:

x - 2 = \frac{3}{7}(2 - 2)

x - 2 = 0

x = 2.

For the y-coordinate:

y - 4 = \frac{3}{7}(18 - 4)

y - 4 = 6

y = 10.

Hence the coordinates are (2,10).
