Practice makes perfect
a Let x represent the ticket prices of students and y represent the ticket prices of adults. We think that 200 students and 150 adults will attend. If we want to raise $1000 and the talent show costs $200, we can write the equation as the following.
Verbal Expression
Algebraic Expression
Revenue from students
200* x
Revenue from adults
150* y
Find the total revenue
200* x+ 150* y
Add the needed money and the cost of talent show
$1000+ $200
Form the equation
200* x+ 150* y= $1200
Thus, the equation is the following.
200x+ 150y= 1200
b Now we will find the interception points of the equation to graph it. Let's start with the x-intercept. In order to find the x-intercept, we will substitute 0 for y and solve the equation for x.
