There are 87 men
3 is the male ratio
You add all the ratios
3+4+5=12
3/12×348
=87
Answer:
3x times 5=5 times 3x
Step-by-step explanation:
Well, you can't really determine the price of 1 book, but you can find out the average cost.
280 - 16 = 8x (x = cost of 1 book)
264 = 8x
264/8 = 8x/8
33 = x
So the average cost of one book is 33$( A little expensive if I do say so myself)
Hope this helped!
