Use the following function rule to find h(-8b). simplify your answer.

h(w), now h(-8b) is another way to say w = -8b, so let's do that substitution then.

I couldb't understand you're question but here are possible answers and explanations

What is the total price: $49.74

$46.49 • 0.07 = 3.25

46.49 + 3.25 = 49.74

What was the sales tax amount: 3.25

$46.49 • 0.07 = 3.25

Hope this helps.
