An electrician charges a set fee for every house call and then charges an hourly rate depending on how long the job takes. let C represent the total cost of the visit when the electrician spends t hours at the house working. A graph of C is shown below. write an equation for C then State the slope of the graph and determine it's interpretation in context of the problem.​

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

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
