So you need to multiply 64 times 12 and she has to pay $768
The best batch size is 1053.
Since 5% have failed, this means 95% have passed the test.
95% = 95/100 = 0.95
We can set up an equation to answer this:
0.95x = 1000
Divide both sides by 0.95:
0.95x/0.95 = 1000/0.95
x = 1052.6 ≈ 1053
How on earth is anyone suppose to answer this !!
24/40 = T/30
40t= 24•(30)
T= 18
Hope this helps. :)
