Mary’s yard is a mess. She needs to hire someone to prune her trees and shrubs. A landscaping service she calls quotes her a pri

ce of $15 consultation fee plus $8 an hour for the actual work. Mary’s neighbor has offered to help her out. She doesn’t charge a consultation fee, but does charge $10 an hour for her work. Who do you think Mary should hire for a 3-hour job? When, if at all, would it be more economical to hire the other service. (Set up and solve a system of equations to answer this question.) a. Mary should hire her neighbor; if there was more than 7.5 hours of work she should hire the landscaping service. b. Mary should hire her neighbor; if there was more than 4.2 hours of work she should hire the landscaping service. c. Mary should hire the landscaping service; if there was more than 7.5 hours of work she should hire her neighbor. d. Mary should hire the landscaping service; if there was more than 4.2 hours of work she should hire her neighbor.

Answer:

Please mark me brainliest and I hoped this helped!

She should ask her neighbor to help her.

Step-by-step explanation:

We can use equations to help us figure out this answer.

8x + 15 = y

10x = y

If she has a 3 hour job, we can use 3 instead of x.

8(3) + 15 = y

24 + 15 = y

30 = y for the landscaping service

10(3) = y

30 = y for a neighbors help

It will cost her 9 dollars less, so she should go with the neighbor.

What is the graph of the linear function that is represented by the equation y= 1/2x-2
kondor19780726 [428]

Answer:

See picture attached.

Step-by-step explanation:

Start with the y-intercept of -2 and plot that on the graph. Then, use the slope of 1/2x to plot more points to help you draw the line. Remember rise over run. Go up one from the y-intercept and right two. If you need to, you can also go down one and left two.

Hope this makes sense.
