I assume #3 is 19 because the slope of the line is still the same.
Hope this is right and it helps! I'm not very sure though.
Answer:
minimum -45, maximum 32
Step-by-step explanation:
C=4x-3y
x≥0, y≥4, x+y≤15
Maximum value of C can be achieved at max x and min y
Minimum value of C can be achieved at min x and max y
So answer is minimum -45, maximum 32

Answer:
The cost of the television is ![\$294](https://tex.z-dn.net/?f=%5C%24294)
Step-by-step explanation:
Let
x -----> the cost of the television in dollars
we know that
The cost of the television represent 100%
<em>If Matt pays cash</em>
then
![100\%-7\%=93\%=93/100=0.93](https://tex.z-dn.net/?f=100%5C%25-7%5C%25%3D93%5C%25%3D93%2F100%3D0.93)
so
The cost is 0.93x
<em>If Matt pays with a loan</em>
then
![100\%+10\%=110\%=110/100=1.1](https://tex.z-dn.net/?f=100%5C%25%2B10%5C%25%3D110%5C%25%3D110%2F100%3D1.1)
so
The cost is 1.1x
The difference between the two methods is
![1.1x-0.93x=0.17x](https://tex.z-dn.net/?f=1.1x-0.93x%3D0.17x)
Remember that
The difference between the two methods is $49.98
so
![0.17x=49.98](https://tex.z-dn.net/?f=0.17x%3D49.98)
Solve for x
![x=\$294](https://tex.z-dn.net/?f=x%3D%5C%24294)
