An electrician charges a flat fee for each job, plus an hourly rate for each hour he takes to complete the job. The total cost of the job can be modeled by the equations y = 50 + 65x. What does the independent variable represent in this situation?

The independent variable = x which represent the the number of hours taken to complete the job.

Step-by-step explanation:

In the given function: y = 50 + 65x, x = Number of hours, y = Total cost of the job.

Here, total  cost of the job depends on the number of hours.

So the independent variable = x which represent the the number of hours taken to complete the job.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
