Question: I'm stuck on this math problem: Diane gave a number train a starting value of 20. This starting value plus half the number was divided by 5 and the resulting value was multiplied by the starting value minus 12. What was the final value of the number train?
Can you help?
Answer: 
If Diane gave a number train a starting value of 20, half the number is 1/2*20=10
The starting value plus half the number is 20+10=30
This starting value plus half the number was divided by 5, giving a total of 30/5 = 6
The starting value minus 12 is 20-12=8
The resulting value after dividing by 5 was times by the starting value minus 12, a total of 8*6 = 48
