Step-by-step explanation: They need to cover expense of $13200. If printing fee is $25 and they sell the books for $40 each, then that means when selling a book they cover expense of printing plus they earn $15 per book.

So if they earn $15 per book that means they have to sell 13200/15=880 books to break even.

If you want to solve this by using equation the this would look like this:

expenses: $13200 + $25x where x is number of books sold

earnings: $40x

Equation:

13200+25x=40x

13200=15x

x=880

Set up the trig equation with the correct values plugged in that you would use to solve for h. (You do not need to solve)

Usimov [2.4K]

From the reference of the 18 degree angle, 'h' is the opposite side and 100 is the adjacent side.

The trig ratio which uses both the opposite and adjacent sides is the tangent.

tan(18) = opp/adj = h/100

Trig equation:
tan(18) = h/100

What is the nth term of 4, 6, 8, 10, 12

Troyanec [42]

$T_n = a_1 + (n - 1)d$

$a_1 = 4 , d = 2$

$T_n = 4 + 2(n - 1)$

$T_n = 4 + 2n - 2$

$T_n = 2n + 2$

--------------------------------------------
Answer: 2n + 2
