HELP! an electrician charges $40 to make a trip to a job site. she charges an additional $50 per hour for three hours or less. if the job takes over three hours, she charges $60 per hour and doesn't charge for the trip. describe the function (write an equation) for each scenario and give the domain and range of each.

three hours or less: 50(x)+40

over three hours: 60(x)

Step-by-step explanation:

x=the number of hours the job takes

I'm not sure how to do the domain and range part. Hope this helps!

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
