Assuming that in the last part of the statement says pencils instead of dollars:

20 pencils for $1.60

1.60 /20 = 0.08 per pencil

For 35 pencils:

0.08 x 35 = $2.8

80 because of you cross multiply 6 times x and 30 times 16 you get 480 and 6 divided by 480 is 80

6/16=30/?
6x=480
Divided by 6
?=80

<h2>Answer: -1.469</h2>

This trigonometric function can be written as:

$tan (3 cos^{-1} (\frac{3}{4}))$ (1)

Firstly, we have to solve the inner parenthesis:

$cos^{-1} (\frac{3}{4})= 41.409$ (2)

Substituting (2) in (1):

$tan (3(41.409))=tan(124.228)$ (4)

Finally we obtain the value:

$tan(124.228)=-1.469$
