Answer: The answer is 7.
Step-by-step explanation:
1*10^-4 equals 0.001 and 7*10^-4 equals 0.007 so 0.007 divided by 0.001 is 7. I hope this makes sense !
$6.75/10 = $.68 per option 1
$7.25/12 = $.60 per option 2
Option 2 is the better buy
Firstly, solve 38C15.
Then solve 42C12.
Compare your answers.
The goal here is to see if 38C15 = 42C12.
Here is the formula:
nCr = n!/(r!(n - r)!
Go for it.
