Suppose x books are produced by both methods.
Total cost for method 1 = 60346 + 10.5x
Total cost for method 2 = 18682 + 21x
Cost of method 1 = Cost of method 2
60346 + 10.5x = 18682 + 21x
60346 - 18682 = 21x - 10.5x
41664 = 10.5x
x = 41664/10.5
x = 3968
For 3968 books produced the cost by both methods will be the same.
Answer:
percentage of 0.9% of 1,000
2*10 =20
4*5 =20
8 *5/2 = 20
answer is B inverse variation, xy = 20
The 2 is the hundredths value.
Hope it helps!
