Jim sold 396 tickets for the school play. Student tickets cost $3 and adult tickets cost $4. Jim's sales totaled $1385. How many
Tamiku [17]
Let student tickets be s and adult tickets be a.  The number of tickets sold of both adult and student then is s + a = 396.  If each student ticket costs $3, then we represent the money equation by tacking the dollar amount onto the ticket.  3s is the cost of one student ticket.  4a is the cost of an adult ticket.  The total money from the sales of both is 4a + 3s = 1385.  We now have a system of equations we can solve for a and s.  If s+a=396, then s = 396-a.  We will sub that into the second equation to get 4a + 3(396-a) = 1385.  Distributing we have 4a+1188-3a=1385.  a = 197.  That means there were 197 adult tickets sold.  If s + a = 396, then s + 197 = 396 and s = 199.  197 adult tickets and 199 student tickets.  There you go!

Tresset [83]

Interpreting the inequality, it is found that the correct option is given by F.

------------------

  • The first equation is of the line.
  • The equal sign is present in the inequality, which means that the line is not dashed, which removes option G.

In standard form, the equation of the line is:

x + 2y = 6

2y = 6 - x

y = -0.5x + 2

Thus it is a decreasing line, which removes options J.

  • We are interested in the region on the plane below the line, that is, less than the line, which removes option H.

------------------

  • As for the second equation, the normalized equation is:

3x^2 + 3y^2 = 12

3(x^2 + y^2) = 12

x^2 + y^2 = 4

  • Thus, a circle centered at the origin and with radius 2.
  • Now, we have to check if the line x + 2y - 6 = 0, with coefficients a = 1, b = 2, c = -6, intersects the circle, of centre x = 0, y = 0
  • First, we find the following distance:

d = \sqrt{\frac{|ax + by + c|}{a^2 + b^2}}

  • Considering the coefficients of the line and the center of the circle.

d = \sqrt{\frac{|1(0) + 2(0) - 6|}{1^2 + 2^2}} = \sqrt{\frac{6}{5}} = 1.1

  • This distance is less than the radius, thus, the line intersects the circle, which removes option K, and states that the correct option is given by F.
