Variables are taken from the first letter of the color, ex: green = g.
Given:
r = g
2r = b = y
Total =42
So then:
r+ r + 2r + 2r = 42
6r = 42
r = 7
y = 2r
y = 2(7)
14 of the 42 pencils were yellow.

Answer:
The forecast is accurate within plus or minus 3.2 units
Step-by-step explanation:
Mean Absolute Deviation is a statistical measure of dispersion from forecast. It measures accuracy level of predicted forecast, by averaging the difference between absolute value of each error from forecasted value.
MAD for a forecast states that : Forecast is accurate within the expected range variation of Mean Absolute Deviation.
So : If the MAD for a forecast is 3.2, we can say that - The forecast is accurate within plus or minus 3.2 units
