The play took in $744 one night. The number of $8 adult tickets was 12 less than twice the number of $5 child tickets. How many
vfiekz [6]

Answer:

68 adult tickets and 40 child tickets were sold.

Step-by-step explanation:

Create a system of equations where a is the number of adult tickets sold and c is the number of child tickets sold:

8a + 5c = 744

a = 2c - 12

Solve by substitution by substituting the second equation into the first one:

8(2c - 12) + 5c = 744

16c - 96 + 5c = 744

21c - 96 = 744

21c = 840

c = 40

So, 40 child tickets were sold. Plug this into the second equation to solve for a:

a = 2c - 12

a = 2(40) - 12

a = 80 - 12

a = 68

So, 68 adult tickets and 40 child tickets were sold.

Answer:

<h2>x = 4, y = 12 → (4, 12)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}10x+2y=64&\text{multiply both sides by 2}\\3x-4y=-36\end{array}\right\\\underline{+\left\{\begin{array}{ccc}20x+4y=128\\3x-4y=-36\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad23x=92\qquad\text{divide both sides by 2}\\.\qquad x=4\\\\\text{put the value of x to the first equation:}\\\\10(4)+2y=64\\40+2y=64\qquad\text{subtract 40 from both sides}\\2y=24\qquad\text{divide both sides by 2}\\y=12
