Question

How many adult tickets were sold?

Answer 1

There are 225 adult tickets sold

Explanation:

First, let’s write down what we know.

Total tickets= 393

There are 57 fewer student tickets than adult tickets (or 57 more adult tickets than student tickets)

Adult tickets - 57 = student tickets which means we can subtract 57 from the total amount of tickets, divide that number by two, then add 57 to find our answer

393 - 57 = 336

336/2 = 168 (This is the amount of student tickets)

168 + 57 = 225 - Our answer!

We can check our answer like this:

225 - 168 = 57 (It is 57 more than the number of student tickets!)

225 + 168 = 393 (And it does equal 393!)

Answer 2

Step-by-step explanation: total number of tickets are 393

let number pf tickets sold to adults be x

and number of tickets sold to students be y

according to question : x + y = 393

x = y - 57 => y-x =57

now we will solve these both equations

x + y = 393 ............(1)

y-x =57 ...........(2)

ADD (1) AND (2)

2y=450

y=450/2

y=225

now put the value of y in any of the equation

x+225=393

x=393-225

x=170

number of adults = 170

number of students = 225
