Question

A school printed 315 tickets to the spring dance. There are 255 tickets left. Which equation can be used to find how many tickets have been sold?

Answer 1

The last choice (x+255=315 )

Explanation:

This is because we know the total number of tickets is 315 and they have 255 left. So, x + 255 = 315. Because you subtracted __ from 315 to get 255. You can rewrite that as __ + 255 = 315 or x + 255 = 315

Answer 2

You didn't add any options but here's one that would work.

315 - 255 = 60

When there is a problem asking how many are left, taken, sold, given, etc. You are usually dealing with subtraction.

Hope that helps and have a great day!
