Answer:
A total of 18 gallons of more gas
Step-by-step explanation:
7 gallons = 210 miles
750-210= 540
210*2 =420 miles 7*2=14 gallons
210/2= 105 7/2=3.5 gallons
525 miles 17.5 miles
210/14= 15 7/14=.5 gallons
540 miles 18 gallons

75% decrease
0.3(n-5)=0.4-0.2
0.3(n-5) = 0.2
Dividing 0.3 both side
(-1,0) and (3,0)
The x-intercepts are the points where the graph crosses the x-axis. (-1,0) and (3,0)
