Answer:
f(4) =2
Step-by-step explanation:
f(x) = 22 - 5x
Let x= 4
f(4) = 22 - 5*4
Multiply first
22 - 20
2
f(4) =2
The first thing you would do is square 17,000, which is 298,000,000. Then you would multiply 298,000,000 by 0.10. (or divide the number by 10)
This would get you 28,900,000.
It would be easier if we list all of the cost involved in the problem statement and add it all up to determine the total cost. We do as follows:
gasoline 29.14
gum 1.10
wiper fluid 4.97
food tax 0.044

total 35.254
