At the movie theatre, child admission is $5.80 and adult admission is $9.60. On Thursday, 167 tickets were sold for a total sale
saveliy_v [14]

Answer:

  93 adult tickets

Step-by-step explanation:

Let 'a' represent the number of adult tickets sold. Then total revenue was ...

  9.60a +5.80(167 -a) = 1322

  3.80a = 353.40 . . . . . . . . . . subtract 968.60, collect terms

  a = 93 . . . . . . . . . . divide by 3.8

93 adult tickets were sold that day.

__

74 child tickets were sold

Simultaneous Equation <br><br> (x+5)(x+2)=65 , xy=24<br><br> Plssss help me ✌
Ne4ueva [31]

Answer:

  • (-11.70, -2.05), (4.70, 5.10)

Step-by-step explanation:

<u>Given equations</u>

  • (x+5)(x+2)=65
  • xy=24

<u>Solving the first equation for x:</u>

  • (x+5)(x+2)=65
  • x^2 + 7x + 10 = 65
  • x^2 + 7x - 55 = 0
  • x = (-7 ± √(49+4*55))/2
  • x = -11.70, x = 4.70

<u>Then solving for y:</u>

  • y= 24/(-11.7) = -2.05
  • y = 24/4.7 = 5.10

<u>Solution set: </u>

  • (-11.70, -2.05), (4.70, 5.10)
