The <em><u>correct answer</u></em> is:
A) 300-70h = 30
Explanation:
The variable h represents the number of hours.
The distance between Mobile and Orlando is 300 km; the bus is traveling at 70 km/h, and for h hours, this gives us the expression 70h for the distance the bus travels.
300-70h gives us the difference between the total distance between the cities and the distance the bus has traveled. Since the bus is 30 km from Orlando, there will be 30 km left; this gives us 300-70h = 30.
the cost of the chocolate of 1 kg will be 30$
Your answer would be 0 and -4. When you plug in 2x - 4 in for the y of the second equation and solve, you get x = 0 and y = -4.
