*Important: From what I can see in this image, this appears to be a test. If this is the case, please do not cheat. In any case, here is the explanation.
What we know:
- Progress has been made to 4.75
- Rate of digging is 3/5 mph
- Depth must be at least 12 1/2
- We need to find the minimum amount of time the machine works
How to solve:
By setting up an algebraic equation, we can solve this.
Process:
- Set up equation 4.75 + 3/5x = 12 1/2
- Convert 19/4 + 3/5x = 12 1/2
95/20 + 12/20x = 250/20
12/20x= 155/20
- Isolate x via division /(12/20) /(12/20)
- +Simplify
x= 12 11/20
Solution: 12 ; 45
1. 20% means 20/100 or 2/10
so 2/10 of 1000=spanish=200=spanish
2.6%=6/100
6/100 times 1000=60
3. so 12%of 6th graders=24
divide by 6
2%of 6th graders=4
multiply by 50
100%of 6th graders=200
200 6th graders
4. so 5%=5/100=0.05
so tax=13.75 times 0.05=0.69
tax=69 cents
13.75+0.69=14.44
