Answer:
$15
Step-by-step explanation:
Let bushes = b and trees = t.
We can write:
12b + 15t = 600 (Equation 1)
8b + 20t = 680 (Equation 2)
24b + 30t = 1200 (Equation 3 -- Multiply Equation 1 by 2)
24b + 60t = 2040 (Equation 4 -- Multiply Equation 2 by 3)
30t = 840 (Subtract Equation 3 from 4)
t = 28 (Divide by 30)
12b + 15 * 28 = 600 (Substitute t = 28 into Equation 1)
12b = 180 (Simplify)
b = 15 (Divide by 12)
Find the mean of the numbers first. The find the difference that each one is from the mean (negative and positive differences). Find the mean of the differences and that is the MAD.
