Modeling Linear Relationships Section 7.1 Modeling Linear Relationships

Objective By following instructions students will be able to: Model linear relationships given limited information.

Explain 1A Given the real-world situation, solve the problem. Fundraising The Band Booster Club is selling T-shirts and blanket wraps to raise money for a trip. The band director has asked the club to raise at least $1000. The booster club president wants to know how many T-shirts and how many blanket wraps the club needs to sell to meet their goal of $1000. The T-shirts cost $10 each, and the blanket wraps cost $25 each. Write a linear equation that describes the problem, and then graph the linear equation. How can the booster club president use the sales price of each item to meet the goal?

Your-Turn #1 Business A sandwich shop sell sandwiches for $5 each and bottles of water for $1 each. The owner of this shop needs to earn a total of $100 by the end of the day. Write a linear equation that describes the problem; then graph the linear equation. Make sure to label both axes with appropriate titles. Then use the graph to determine how many sandwiches the shop must sell if no waters are sold.

Revisit Objective Did we… Model linear relationships given limited information?
