Answer:
a) Y = 35,422.12
b) Y = 29,367.67
c) 1,210.89
Step-by-step explanation:
The salary of teachers is forecasted by the following equation,
Y = 23,313.22 + 1,210.89X
Where Y is the forecasted salary and X is the years of experience.
(a) If a teacher has 10 years of experience, what is the forecasted salary?
Here we have X = 10
Y = 23,313.22 + 1,210.89(10)
Y = 23,313.22 + 12,108.9
Y = 35,422.12
(b) If a teacher has 5 years of experience, what is the forecasted salary?
Here we have X = 5
Y = 23,313.22 + 1,210.89(5)
Y = 23,313.22 + 6,054.45
Y = 29,367.67
(c) Based on this equation, for every additional year of service, a teacher could expect his or her salary to increase by how much?
For every additional year of service, a teacher could expect an increase of 1,210.89.
