Ally got a raise in her monthly pay, from $15.90 to $17.95 . what is the increase percent ?

The percentage increase in Ally monthly pay is 12.89 %

Step-by-step explanation:

Given as :

The initial pay of Ally = i = $ 15.90

The final pay of Ally =  f = $ 17.95

Let The increase percentage = x %

Now, Percentage increase % = × 100

Or, x   = × 100

Or, x  = × 100

Or, x  = × 100

∴   x = 0.1289 × 100

I.e x = 12.89

So, increase percentage = x = 12.89

Hence The percentage increase in Ally monthly pay is 12.89 % Answer

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.
