Ike Phillips worked 6.7 hours at time-and-a-half pay and 3.4

ikadub [295]

Working out the different pay rates earned by Ike Phillips :

Time and half pay rate = $17.055
Double pay rate = $22.74
Time and half earning = $114.2685
Double rate earning = $77.316
Gross earning = $646.3845

Let :

Regular rate = $11.37

Total earning for the week = $454.80

Double pay hours = 3.4

Time and half pay hours = 6.7

Time and half pay rate = 1.5 × regular pay rate = 1.5 × 11.37 = $17.055

Double pay rate = 2 × regular pay rate = 2 × 11.37 = $22.74

Time and half earning = rate × time = $17.055 × 6.7 = $114.2685

Double rate earning = rate × time = $22.74 × 3.4 = $77.316

Gross earning = (regular + time and half + double earning) = $(454.80+114.2685+77.316) = $646.3845

Therefore, Ike's gross earning for the week is $646.3845

If f(x) is a linear function, f(−2)=4, and f(1)=−1, find an equation for f(x)

juin [17]

Answer:

$y = -\frac{5}{3}x+\frac{2}{3}$

Step-by-step explanation:

Given

$f(-2) = 4$

$f(1) = -1$

Required

The equation of the function

The given parameters means that:

$(x_1,y_1) = (-2,4)$

$(x_2,y_2) = (1,-1)$

Calculate the slope (m)

$m = \frac{y_2 -y_1}{x_2 -x_1}$

$m = \frac{-1-4}{1--2}$

$m = \frac{-5}{3}$

The equation is then calculated using:

$y = m(x - x_1) + y_1$

This gives:

$y =\frac{-5}{3}(x--2)+4$

$y =\frac{-5}{3}(x+2)+4$

Open bracket

$y = -\frac{5}{3}x-\frac{10}{3}+4$

Take LCM

$y = -\frac{5}{3}x+\frac{-10+12}{3}$

$y = -\frac{5}{3}x+\frac{2}{3}$
