If 1 lanyard = 1.75 ft, then 1000 lanyards = (1000 x 1.75) = 1750 ft
Answer: ![\frac{219}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B219%7D%7B100%7D)
======================================================
Explanation:
Think of
as
or
This works because dividing anything over 1 does not change the original number.
Then we can move the decimal point two spots to the right for each number
- 2.19 becomes 219
- 1.00 becomes 100
Therefore, ![2.19 = \frac{219}{100}](https://tex.z-dn.net/?f=2.19%20%3D%20%5Cfrac%7B219%7D%7B100%7D)
8% of 20 is 1.6
This is because you take the percentage and divide it by 100 so that you have a decimal, then multiply that by twenty. So, 8% ÷ 100 = 0.08 then 0.08 × 20 = 1.6
Hope this helps!
4(x-4)
Factor out 4 from both terms.
Let e be the minimum number of workers needed.
e(100-3)/100≥215
97e/100≥215
97e≥21500
e≥21500/97
e≥221.6
Since the number of employees must be an integer...
e≥222
So the minimum number of employees needed is 222.
