Mr. Smith wants to spend less than $125 at a zoo. A ticket cost $7 he is taking 2 kids with him. Use p to represent the other money he can spend there.

2 kids and Mr. Smith = 3 people.
Total Ticket Cost is 3 people * 7 per ticket = 21

If he has 125 to spend, we have the following inequality using less than or equal to (<=) since he can spend up to or less than 125:
p + 21 <= 125

Subtract 21 from each side:
p <= 104
