Answer:
D.) $12n + $8u = 112 ;u = 4 + n
Step-by-step explanation:
Given that :
Cost per new books (n) = $12
Cost per used book (u) = $8
Total revenue earned = $112
store sold 4 more used books than new books
Hence,
Total revenue should be :
Revenue from new books + Revenue from used book = total revenue
Revenue from new books = $12 * n = $12n
Revenue from used books = $8 * n = $8n
$12n + $8u = 112
Number of books sold :
Number of used books sold = 4 + number of new books sold
u = 4 + n
X= -12.5 you add (4+3) then, you combine it with 18 to get 25, then you divide 25 by -2x
A. -20,-12,-8,-1,(1),5,10,x,x........ur other 2 numbers have to be greater then 1
B. x,-20,-12,-8,(-3),-1,1,5,10......ur other number has to be less then -3
