Answer:
Substitute the values given for f(x) and g(x), in 1. they say f(x)=4x and g(x)=1-x
and basically just substitute them for the functions themselves.
4x+1-x
add like terms!
4x-x = 3x!
3x+1 is your simplified answer, since it is an expression it cannot be simplified any further.
The equation to solve this would be:
-4+x=25
Solve for x.
Add 4 to both sides.
(-4+x)+4=(25)+4
x=29
The overall change to account was $29.
Hope this helps.

Combine costs
59.99(3) + 75 = 179.97 + 75
179.97 + 75 = $254.99 (total cost)
Now add tax: 8% = 0.08
254.99 * 0.08 = 20.3992
254.99 + 20.3992 = 275.3892
Solution: bill would be around $275
