Answer:
For 3 hours of plumbing work or less, Clyde's Plumbing Company would be less expensive than We-Unclog-It Plumbers.
Step-by-step explanation:
To determine for how many hours of plumbing work Clyde's Plumbing Company would be less expensive than We-Unclog-It Plumbers, we need to compare the total costs of the two companies.
Clyde's Plumbing Company charges a $75 per visit fee that includes one hour of labor, plus $45 per hour after the first hour.
We-Unclog-It Plumbers charges a $100 per visit fee that includes one hour of labor, plus $40 per hour after the first hour.
Let's call the total number of hours of plumbing work "x".
For Clyde's Plumbing Company, the total cost would be:
$75 + $45(x-1) = $75 + $45x - $45 = $30 + $45x
For We-Unclog-It Plumbers, the total cost would be:
$100 + $40(x-1) = $100 + $40x - $40 = $60 + $40x
To find the number of hours where Clyde's is less expensive, we set the two expressions equal to each other:
$30 + $45x = $60 + $40x
$15 = $5x
x = 3
Therefore, for 3 hours of plumbing work or less, Clyde's Plumbing Company would be less expensive
