The cost in dollars is given as 50 + 0.50x, so ...
f(x) = 0.50x +50
B) You want to find x for f(x) = 100. Substitute the given numbers and solve for x.
100 = 0.50x +50
50 = 0.50x
50/0.50 = x
100 = x
You drove 100 miles during the week if the cost was $100.
4(x-5)=24 would be your answer.
The answer is really simple just do 3 plus 5 which is 8 so the answer is 8x
I don’t understand the question
