Members of the math club at Morganson Middle School sent us this problem: The math club took a field trip to see the movie An Inconvenient Truth. A total of 28 people went on a trip, including students, teachers, and parents chaperones. There were more parents than teachers. Movie tickets cost $7, but the students got a discount and only had to pay $3 each. The group paid a total of $108 to get everyone in. Determine how many students, how many teachers, and how many parents went on the trip.

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

true

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
