Hey,
So like in the previous question he has to pay a fixed fee right?
So we have to subtract 7.50(the fee as mentioned in the question )
And then we know that each ticket costs 35.25 right?
That means we have to divide the answer we got (430.50-7.50) by 35.25 OK?
So if we do that we get the answer.
So if I take the answer as B I can say:
B=(430.50-7.50)/35.35.
Theo’s brackets means that you have to do those first.
Hope this helps !
