Algebra 1A: Week 8 Classwork 3 Part 2

Your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that 200 adults and 250 children will attend. Let x represent the cost of an adult's ticket and y represent the cost of a child's ticket.

Write an equation in standard form that can be used to find out what ticket prices to set in order to raise $4,000.

•  $200x+250y=4000$  

•  $250x+200y=4000$  

•  $200x+250y=450$  

•  $x+y=450$

Your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that 200 adults and 250 children will attend. Let x represent the cost of an adult's ticket and y represent the cost of a child's ticket.

Use your standard form equation that you wrote for #1 to find the x-intercept. Interpret in context.

• (20, 0); If children's tickets are $0, adult tickets need to be $20 to reach the goal of $4,000.

• (0, 20); If adult tickets are $0, children's tickets need to be $20 to reach the goal of $4,000.

• (200, 0); If 200 adults come to the dinner, children can eat for free.

• (16, 0); If children tickets are $0, adult tickets need to be $16 to reach the goal of $4,000.

• (20, 0); If children's tickets are $0, adult tickets need to be $20 to reach the goal of $4,000.

• (0, 250); If 250 children show up to the dinner, adults can eat free.

You are purchasing school supplies. Each notebook costs $1.50 and each pen costs $0.50. You have $9.00 to spend. Let x represent the number of notebooks you purchase, and y represent the number of pens you purchase.

Write an equation in standard form to model this situation.

•  $1.50x+0.50y=9.00$  

•  $0.50x+1.50y=9.00$  

•  $y=0.50x+1.50$  

•  $y=1.50x+9.00$
