Answer:
297 miles
Step-by-step explanation:
cost = 0.78 cents per mile + base fee
y = 0.78x + 15.88
247.65 = 0.78x + 15.88
subtract 15.88 from both sides
231.77 = 0.78x
divide by 0.78 on both sides
x = 297.14120256
297 miles
Answer:
741,361,247
Step-by-step explanation:
Let the numbers be x,y,z and x>y>z
x+y+z=1349
x=3z
y=2z-133
3z+2z-133+z=1349
6 z=1349+133
6 z=1482
z=247
x=3*247=741
y=2*247-133=494-133=361
