Question

A total of 611 tickets were sold for the school play. They were either adult tickets or student tickets. There were 61 more student tickets than adult tickets. How many adult tickets were sold?

Answer 1

Adult tickets=275

Explanation:

form 2 equations from the given info.

x+y=611

y=x+61

x being the adults and y being the students tickets

then substitute the y equation into the first equation.

x+x+61=611

2x+61=611

2x=550

x=275

and you can check by putting 275 back into the original equations :)
