The right amount to test would be 30.
200 is to many kids and 12 is not enough.
Hope this Helps!!
If anything is above 5 it will round up
It's <em>370,000.00000...</em> with as many zeros as you want after the decimal point.
Factors of 15 - 1, 3, 5, 15
Factors of 18 - 1, 2, 3, 6, 9, 18
Factors of 30 - 1, 2, 3, 5, 6, 10, 15, 30
Your answer is D
Hope I helped you :-)
