Question

total of 640 tickets were sold for the school play. They were either adult tickets or student tickets. There were 60 fewer student tickets sold than adult tickets.
w many adult tickets were sold?

Answer 1

380 adult tickets.

640 divided into the sub categories of student and adults would be 320. at this point you don't even have to do any of the math for students because you already know there would be 60 less student tickets so you can just add the 60 to 320 for adults. So 380
