Answer:
function a is faster
Step-by-step explanation:
We know that there are two tickets (which we'll represent with x) and a fee for transporation (which is $20)
So we can set up the equation 20+2x=48
We want to isolate x so we'll subtract 20 from each side, which gives us the equation
2x=28
Then divide each side by 2
Giving us the final answer of
x=14
So each ticket costs $14
