Answer:880
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
Answer:
223 (rounded to closest one) actual answer would be 222.91479275
Step-by-step explanation:
use formula A=Pe^nt
$280 = Pe^0.019(12)
$280 = Pe^0.228, then evaluate the solution by isolating the variable and dividing each side by the factors which don't contain the variable.
P = 222.91479275
Answer:
91/6 times
Step-by-step explanation:
(2/3)(x)=3/8
2x/3=3/8
16x=9
x=9/16
So, 2/3 goes into 3/8, 9/16 times
