(a)
Part A
What is the cost of Hannah's order if she buys 9 books?
$
Part B
Write a sentence to describe how you calculate the cost of Hannah's order.

Part A:

1 book -- $7.25

9 books -- (9 * 7.25) = $65.25

And shipping fee -- (65.25 + 6.75) = $ 72

Part B

9 multiplied by the cost and added with the shipping fee to get Hannah's total cost.

Thenks and mark me brainliest :))

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
