The sales tax rate would be 7%
23.54 - 22 = 1.54
1.54 / 22 = .07
.07 = 7%
Answer:
f(4) = g(4) and f(0) = g(0)
Step-by-step explanation:
In order for f(x) = g(x), the value of x must be the same in both functions:
f(4) = g(4) . . . corresponds to x=4
f(0) = g(0) . . . corresponds to x=0
The graph is not shown here, so we cannot say if these are the appropriate solutions. We can only say that the other choices are not.
f(x) = g(x) if ...
f(4) = g(4) and f(0) = g(0)
__
Something like f(0) = g(4) is useless for finding solutions to f(x) = g(x).
Answer: 7000
Note: 5 and up rounds up. 4 and below rounds down.
4 < 5 so that means we won't need to round up we round down.
7412 = 7000
If we were to round up then the answer would of been 7500.
Add 10 to both sides of the equation
