Explanation:
You are planning a skating party at a rink that charges a basic fee of $8.00 and $4.00 per person for catered parties. You don't want to spend more than $68.00. Write and solve the inequality to find the number of friends you can invite.
4x + 8 ≤ 68
subtract 8 from both sides:
4x + 8 - 8 ≤ 68 - 8
4x ≤ 60
divide both sides by 4:
4x/4 ≤ 60/4
x ≤ 15
