PLEASE HURRY!!

Sarah has been running a dog-walking business since 2010. She walks dogs twice a day, takes them to the park, and returns them to their homes. Each year, she has increased her fee by the same amount. The table shows what Sarah charged each customer for two given years of her business:


Year Annual Dog-walking Fee

2010 $350

2014 $750

SHOW YOUR WORK!!

AWhat is the rate of change and initial value for Sarah’s business? How do you know?
BWrite an equation in slope-intercept form to represent the fees that Sarah charges each year

Verified Answer :

ABusiness means the process of earning money, so she earned $350 at first time, so her initial value would be: $350

Rate of change = 750 - 350 / 350 100
= 400 / 350 100
= 40000 / 350
= 114.28

Now, There are 4 years between 2014 & 2010 so it will be:
= 114.28 / 4 = 28.57

In short, Your Answer would be 28.57% per year

B) Equation would be: Y = x + 0.2857x
Where, x = number of year

Hope this helps!

Answer:

look down!!!

Step-by-step explanation:

rate = the cost of walking the dog + 100$ || initial = 350$

The equation for this would be  y = 100x + 350

a= 350 is initial no math needed and 100 is the rate as in 2010 cost was 350 now its 750 100 each year...

b= y = 100x+350
