Using the equation y+=+45%2B30x+if an electrician works 3 hours on a job, how much will the bill be?
y+=+45%2B30x+......if x=3, we have
y+=+45%2B30%2A3+
y+=+45%2B90+
y+=+135+
Using the equation y+=+45%2B30x, if you have a budget of 300.00 dollars for this job, what is the most full hours the electrician can work?
y+=+45%2B30x+......if y=300.00, we have
300.00+=+45%2B30x+
300.00+-45=30x+
255=30x+
x=255%2F30
x=8.5->the most full hours the electrician can work is 8 hours
