Answer:
x=28 so they need to charge 28 tickets
Explanation:
525 + 12.50x=875
First, take the 525 and drag it to the other side which will become into negative so the equation will be 12.50x=875-525 now just subtract it and u will get the answer of 12.50x=350 now all you need to do is divide
and now the answer will be x=28 to double check we can just multiply 12.5 times 28 = 350 now plus 525 is = to 875 hope this helped :>
