☆☆☆☆☆☆☆☆☆☆☆☆☆☆A. y =-5/8x + 6
B.y =-5/8 x + 16
C. y = -15/2x – 49
D. y =-15/2 x + 71
Answer:
4 and -3 if im not wrong......
Answer:
C. 
Step-by-step explanation:
Let x represent number of miles.
We have been given that a taxi cab charges $1.50 for the flat fee and $0.50 for each mile.
The cost of riding x miles would be
and the total cost of riding x miles would be
.
Since Sharon has only $25 to spend on the taxi ride, so the cost of riding x miles on taxi must be less than or equal to 25.
We can represent this information in an inequality as:

Therefore, option C is the correct choice.
You can do this by taking away the second equation from the first to get rid of the x terms so:
7x - 7x = 0
-5y - -9y = - 5y + 9y = 4y
22-6 = 16
So you are left with the equation:
4y = 16
Divide both sides by 4 to find y
y = 4
