Answer:
Cost of 1 bushes = a = $9
Cost of 1 tree = b = $73.5
Step-by-step explanation:
Given:
13 bushes and 4 trees cost = $411
Missing;
6 bushes and 2 trees cost = $201
Find:
Value of bushes and tree
Computation:
Cost of 1 bushes = a
Cost of 1 tree = b
So,
13a + 4b = 411 ...........eq1
6a + 2b = 201 ................eq2
From Eq1 and Eq2
Cost of 1 bushes = a = $9
From eq 1
13a + 4b = 411
13(9) + 4b = 411
Cost of 1 tree = b = $73.5

Answer:
$450.00

$10.00*40=$400
$400 + ($5.00 *10) = $450
Answer:
See below
Step-by-step explanation:
This is a bowl shaped parabola ( due to the positive coefficient of x^2)
the minimum value (vertex )
will occur at x value = - b/2a = - -4600/2(415) = 5.54 years
the minimum VALUE will be the quation with this value of x inserted
415 (5.54)^2 - 4600(5.54) + 200 000 = $ 187 253.01
The home will reach a minumum value of 187253.01 in 5.54 years
