For me to solve the system of equations for the total cost of lawn care using the tequnique substitution am I right to say:

c=$200+$50h
c=$300+$25h
would be
c=$250
c=$325

To solve the system of equations using the substitution method, you need to follow these steps:

Step 1: Start with one of the equations and solve it for one variable in terms of the other variable.

In this case, let's start with the first equation:
c = $200 + $50h

Step 2: Substitute the expression you found for the variable in the other equation.

Substitute the expression for 'c' in the second equation:
($200 + $50h) = $300 + $25h

Step 3: Solve the equation for the remaining variable.

Let's solve for 'h' by simplifying the equation:
$50h - $25h = $300 - $200
$25h = $100
h = $100 / $25
h = 4

Step 4: Substitute the value of the variable you found back into one of the original equations to solve for the other variable.

Substitute the value of 'h' in the first equation:
c = $200 + $50(4)
c = $200 + $200
c = $400

So, the solution to the system of equations is:
c = $400
h = 4
