If we let x as the cost for labor per hour, then the total cost for labor is
400/60 x
2x/3
If we let y as the earnings per hour, then the gross earnings is
400/60 y
2y/3
The inequality then is
2y/3 - 2x/3 ≥ 35 <span />

Answer:
4.21, 4.22, 4.23, 4.24
Step-by-step explanation:
We're given:
- The number is bigger than
- The number is smaller than 4.25
is 0.2.
How do we know this? Think about 100%. When we divide 100% by 5, we get 20%. 20% in decimal form is 0.2.
This means that is the same as 4.20.
What's a number with two decimal places that's greater than 4.20, but less than 4.25?
Come on, Kat ! The question tells you everything you could
possibly want to know, except what's for dinner tomorrow.
It gives you the formula at the bottom.
The formula is:
Interest = (Principle) x (Rate) x (Time) .
Above that, in the story, it gives you 3 of the 4 quantities in the formula:
Interest = $656
Principle = $1,000
Rate = 4.1% (that's 0.041)
Do you think you could write those numbers into the formula,
and find out what the (Time) is ?
656 = (1,000) x (0.041) x (T)
Divide each side by 41 .
You're welcome.
