Question

You are ordering concert tickets. You pay a processing fee of $5, plus $18 per ticket. How many tickets can you buy for $100?

Answer 1

You can buy 4 tickets.

5+18=23
100/23= approx. 4.34

(you can buy 4.34 of a ticket, so you round down)

so 4 tickets is the answer

Answer 2

You can buy 4 tickets.
One ticket is $23 (8+5)
23 goes into 100 4 times (92)

Also that rounds to 25 (like a quarter)
A quarter goes into a dollar 4 times.
BAM! 4 times, easier way
