Question

A total of 487 tickets were sold for the school play. They were either adult tickets or student tickets. There were 63 fewer student tickets sold than adult tickets. How many adult tickets were sold?

Answer 1

s=a-63

s+a=487, using s from above in this equation you get:

a-63+a=487 combining like terms

2a-63=487  adding 63 to both sides

2a=550  dividing both sides by 2

a=275

So there were 275 adult tickets sold.
