- 1 < - x/3 < 1
1st. Multiply all parts by 3:
-3 < - 3x/3 < 3. Simplify the mid term:
-3 < -x < 3. Now multiply all terms by - 1. Note when you multiply by a negative number, you flip the inequality signs:
(-1)(-3) < (-1)(-x) < (-1)(3)
+3 > x> -3

Answer: The cost of renting the car for one day and driving at 75 miles = $ 47.5 .
Step-by-step explanation:
GIven: Daily cost of renting car = $ 25.00 + $0.30 per mile driven
Let x = Total distance traveled ( in miles).
Then total cost of renting (in $)= 25+0.30x
For x= 75 miles
The total cost of renting (in $)= 25+0.30(75)
=25+22.5
= $47.5
Hence, the cost of renting the car for one day and driving at 75 miles = $ 47.5
The answer is 1.10 because you have $90 you give away fifty
