Answer:
the number of miles is 160
Step-by-step explanation:
The computation is given below:
Let us assume the miles be x
For company A
y = $100 + $0.40x
And, for company B
y = $20 + $0.90x
In order to find out the number of miles, the rental cost of the company A should be less than the company B rental cost
SO,
$20 + $0.90x > $100 + $0.40x
Subtract $20 from both sides
0.90x > 80 + 0.40x
Now subtract 0.40x from both sides
0.50x >80
x>160
So the number of miles is 160
You will at 7 to both sides and then divide 2 on both sides to find x. :)
2x-7=3
+7=+7

2x = 10

X = 5
Yes he does.
If the sales tax is 6%, that means that he has to pay an extra 6 cents for every dollar.
6x7.5=45
$7.50+$0.45=$7.95
Answer:
y = 3x - 11
Step-by-step explanation:
y=mx+b
1=3(4)+b
1=12+b
b=-11
