Last month, Luke spent $1,300 on his mortgage (home loan payment), $320 for food, $280 on entertainment, $275 for his car payment, $60 on car insurance, and $75 on clothing. What was the difference for the month between his fixed expenses and
variable expenses?
A)
$1035
B)
$1240
C)$960
D)
$900

The difference between the two categories is 960.

The fixed expenses are: mortgage, car and insurance

1300 + 275 + 60 = 1635

The variable expenses are: food, entertainment, clothing

320 + 280 + 75 = 675

Subtracting those gives a value of 960.

Step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75
