Answer:
The amount driven would be 275, and the cost for both plans will be 77.75$
Step-by-step explanation:
make both equations
y=0.09x+53
y=0.13x+42
set them equal to each other and solve for x to get the distance
take that number and put it in one equation and solve for y to get the price of the plan for that value
-10p+9=12
-9 -9
-10p=3
—— —
-10 -10
P=3/-10 or -0.3
9.42 is the circumference, for future refernce its just pi times diameter :)
The answer would be 5x10^4
