Question

Jacob charges $10 per hour to babysit and $60 to clean the house. Write the expression which represents Jacob's earning for cleaning one house and babysitting?

Answer 1

60 + 10h

Explanation:

Since cleaning the house is a flat fixed cost ($60 no matter how long it takes), you dont use a variable to find it. For baby sitting on the other hand, the cost of it is reliant on how long you do it ($10 for every hours). Therefore you need to use a variable (h).

I hope this helps!
