mike and kim invest $14,000 in equipment to print yearbooks for schools. each yearbook costs $7 to print and sells for $35. how
Zina [86]
The answer is A.) 500 Year books.

The profit they would gain from each year book would be $28 since each year book costs $7 to make and sells for $35. You would simply divide 14,000 by 28 to find how many books they would need to sell in order to get their investment back which would be 500 books. 

Hope this helps.

A regular hexagon is shown below. Find the value of X
Varvara68 [4.7K]

Answer:

x=9

Step-by-step explanation:

The expression is for the interior angle of the hexagon; one interior angle is equal to (11x+21)^o.

Since an interior angle of a hexagon measures 120°, we have the equality

(11x+21)=120.

Now it is just a matter of solving for x:

11x=120-21\\\\11x=99\\\\x=\frac{99}{11} \\\\\boxed{x=9}

coldgirl [10]

Answer: -4t + 1590

Step-by-step explanation:

Given : Josh works as a tutor for $11 an hour and as a waiter for $15 an hour.

Then, the total money earned this month ( in dollars)

= 11 (No. of hours worked as a tutor)+ 15 (No. of hours worked as a waiter)

=11(t) + 15(106-t)

= 11t+1590-15t

= -4t+1590

Hence, the expression for the combined total dollar amount he earned this month =

How do I do this like I'm so confused
DIA [1.3K]
So right now it is telling you that out of 60 books, 24 are nonfiction. Therefore that is 24/60. 40% of 60 is 24 so that means the other 60% is nonfiction. Hope this isn't confusing and it helps.
