Tom has just received a new job offer he is told that his salary will be 75,000.00 per year he is also told that his salary will probably be 83,000.00 in four years assume that y= toms salary amount in dollars and x= the number of years worked 1. use data given to find rate of change, or the salary increase per year (hint: commute the slope.) 2. use data given and the slope vale from step 1 to write the slope- intercept form of the line. 3. based on your equation from step 2 what will toms salary be in ten years?

Solution-

Here,

x = number of years worked,

y = salary in dollars.

Tom is getting $75,000 of salary right now, so for this case,

x₁ = 0,

y₁ = 75000

Tom will be getting a salary of $83,000 after 4 years from now, so for this case,

x₂ = 4,

y₂ = 83000

1.

Rate of change of salary = slope of the line joining (x₁, y₁), ( x₂, y₂)

∴ The salary increase per year is $2000.

2.

Equation of the line in slope-intercept formula,

Putting x₁ = 0, y₁ = 75000, we get

3.

Putting x = 10, we can compute the value of y to get the salary after 10 years.

∴ Tom's salary in ten years will be $95,000

when x=0.

when x=4.

1.Rate of change=

2. Slope intercept form of salary and number of years

   →[as slope =2,000]

→y-75,000=2,000 x

→y= 2000 x+ 75,000

3.Tom salary after 10 years ,

put x=10

y=2000×10+75,000

y=20,000+75,000

y=$95,000

Salary after 10 years=$95,000

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
