The cost of traveling 25km would be $3000.
You can travel 35 km for $4200.
Step-by-step explanation:
Consider the provided information.
For 30km cost $3,600.
30 km = $3600
Divide both sides by 30.

....(1)
The cost of 1 km is $120.
Part (A) what would be the cost of traveling 25km
Multiply both the sides of equation 1 by 25.
25 km = 3000
Hence, the cost of traveling 25km would be $3000.
Part(B) How far could you travel for $4,200?
Divide 4200 by 120.

Hence, you can travel 35 km for $4200.

Answer:
10 years old
Step-by-step explanation:
Let's say the age of the younger sister is x. Then the age of the older sister must be x + 2 because the ages are consecutive <em>even</em> numbers.
"Twice the age of the youngest exceeds the oldest by 8" means that we multiply x by 2 and set that equal to (x + 2) + 8:
2x = (x + 2) + 8
2x = x + 10
x = 10
So, the youngest sister is 10 years old.
