Answer:
8
Step-by-step explanation:
We are required to evaluate:
0.1m+8-12n
When ![m=30, n=\frac{1}{4}](https://tex.z-dn.net/?f=m%3D30%2C%20n%3D%5Cfrac%7B1%7D%7B4%7D)
Substituting these values into the expression, we have:
![0.1m+8-12n=0.1(30)+8-12(\frac{1}{4})\\=3+8-\frac{12}{4}\\=3+8-3\\=8](https://tex.z-dn.net/?f=0.1m%2B8-12n%3D0.1%2830%29%2B8-12%28%5Cfrac%7B1%7D%7B4%7D%29%5C%5C%3D3%2B8-%5Cfrac%7B12%7D%7B4%7D%5C%5C%3D3%2B8-3%5C%5C%3D8)

Answer:
- w + b = 13
- 6.5w + 2b = 57.5
Step-by-step explanation:
Let w represent the number of gifts wrapped. Let b represent the number of bags prepared.
w + b = 13 . . . . gift bags and gifts wrapped
6.5w +2b = 57.5 . . . . total time spent preparing gifts
_____
Lincoln wrapped 7 gifts and bagged 6.
(100+3-4(4-5))/(6+5+5+5+300)
=(100+3-16+20)/(321)
=(107)/(321)
=1/3
