Sierra is going on a field trip that costs $48. The cost includes $20 for transportation and two tickets that each cost the same amount. How much does each ticket cost?

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
