5 dollars because the magazine was one dollar so then you have 20 dollars left. 20 dollars to buy 4 erasers would equal 5 dollars each.

Each eraser is $5. because a magazine is $5, you're left with $20. 5x4=20.

g(- 2) = - $\frac{43}{16}$

Step-by-step explanation:

Using the rules of exponents

$a^{-m}$ = $\frac{1}{a^{m} }$ and $a^{0}$ = 1

Given

g(x) = 5 $x^{-4}$ - 3 $x^{0}$ , then

g(- 2) = 5 $(-2)^{-4}$ - 3 $(-2)^{0}$ = $\frac{5}{(-2)^{4} }$ - 3(1) = $\frac{5}{16}$ - $\frac{48}{16}$ = - $\frac{43}{16}$
