An irrational number is a number that can't be expressed in form of a/b. Where b does not equal 0. And -16 can be expressed in the form of a/b. So no, it is not an irrational number.
6.50 + 1.50 = 8
8 × .20 = 1.6
8 × .7 = .56
8 + 1.6 + .56 = $10.16
The total cost is $10.16.

Answer:
Cost of shrubs = 23
Cost of tree = 47
Step-by-step explanation:
Let
Cost of shrubs = x
Cost of tree = y
13x + 4y = 487 (1)
6x + 2y = 232 (2)
Multiply (2) by 2
12x + 4y = 464 (3)
13x + 4y = 487 (1)
Subtract (3) from (1)
13x - 12x = 487 - 464
x = 23
Substitute x = 23 into (2)
6x + 2y = 232 (2)
6(23) + 2y = 232
138 + 2y = 232
2y = 232 - 138
2y = 94
y = 94/2
= 47
y = 47
