Answer 1

Greetings!

Answer:

$35.96 to 2.d.p. or 36 to 2.s.f.

Explanation:

We can show this by:

611 = 78x

x being the 78 students

To find 1x which is the price of one student, or one lunch, we can simply divide both sides by 78:

`(611)/(78) = (78x)/(78)`

Or:

35.95 = 1x

So each lunch cost 35.96 to 2.d.p. or 36 to 2.s.f.

Hope this helps!
