Answer:
6000
Step-by-step explanation:
Each mp3 sells at $120 per mp3 player multiply that by 100 its $12000
It cost them $45 per mp3 to be made multiply that by 100 its $4500 then add the $1500 for the week and its $6000
$12000-$6000=$6000
They make a profit of $6000 in a week
The cost of company 1: 10x+50
The cost of company 2: 8x+60
The cost will be the same at:
![10x + 50 = 8x + 60 \\ 2x = 10 \\ x = 5](https://tex.z-dn.net/?f=10x%20%2B%2050%20%3D%208x%20%2B%2060%20%5C%5C%202x%20%3D%2010%20%5C%5C%20x%20%3D%205)
The answer is 5 hours
3276800/8 = 409600 (how many bacteria in an hour)
Then just multiply that number by the amount of hours you want to solve for
9 hours = 3686400
10 Hours = 4096000
Y = 3.5x
24= 3.5x
the train will be ride 6 times each day
and there are 7 days in a week
so multiply 6 and 7
=42
