You have just received advertisements from 2 companies in your area: Greener Lawns and Lawns for Less. Greener Lawns charges an initial fee of $200, plus $50 per hour for labor costs. Lawns for Less charge an initial fee of $300, plus $25 per hour for labor costs.

1. If h represents the number of labor hours and C represents the cost, write the total cost equation for Greener Lawns.

2. If h represents the number of labor hours and C represents the cost, write the total cost equation for Lawns for Less.

3. Solve the system of equations for the total cost of lawn care using the desired technique: substitution, elimination, or graphing.

4. Document how you came to these conclusions for accuracy.

1. C = 50h + 200.

2. C = 25h + 300.

3. Eq1: C = 50h + 200.

Eq2: C = 25h + 300.

Substitute 50h + 200 for C in Eq2:

50h + 200 = 25h + 300,

50h - 25h = 300 - 200,

25h = 100,

h = 4.

Substitute 4 for h in Eq1:

C = 50*4 + 200 = 400.

4. The Substitution and Elimination

Methods are more accurate than graphing.
