1. LESSON 2.06: Modeling Linear Relations MFM1P

2. Discuss some cost that may be associated with renting a hall for a wedding or banquet.

5. Ralph’s Rental has many tools that are available for rent. They charge $20 fixed price plus $5 per hour for the rental of their post hole digger. This situation can be represented by the equation C = 5 n + 20.

7. C = 5 (0) + 20 C = 5 (1) + 20 C = 5 (2) + 20 C = 5 (3) + 20 C = 5 (4) + 20 C = 5 (5) + 20 C = 5 (6) + 20 C = 5 (7) + 20 C = 5 (8) + 20

8. FIRST DIFFERENCES 25 - 20= 5 30 - 25= 5 35 - 30= 5 40 - 35= 5 45 - 40= 5 50 - 45= 5 55 - 50= 5 60 - 55= 5

9. In general, we can make a few notes about our equation and how it relates to the description given in the example.

10. Summary: Equations can be developed from written descriptions using the general formula below. COST = Price per unit x Variable + Fixed Cost

11. Brandon and Beyonce are looking at renting a hall for her their wedding. The hall charges a maintenance fee of $300 and a cost of $25 per plate for supper. Write an equation to model this situation. C =25 n + 300.

13. C =25 (0) + 300 C =25 (10) + 300 C =25 (20) + 300 C =25 (30) + 300 C =25 (40) + 300 C =25 (50) + 300 C =25 (60) + 300 C =25 (70) + 300 C =25 (80) + 300
