Answer:
3r + 12 ≤ 30
Explanation:
He can spend at most $30, so the amount he can spend is less than or equal to (≤) $30.
amount he will spend ≤ 30
Let r = number of rides.
The amount he will spend is composed of 2 parts:
(a) a fixed cost of $12.00, or just 12.
(b) a per ride cost of $3.00, or 3r.
amount he will spend = 3r + 12
Since we know the amount must be less than or equal to $30.00, the inequality is:
3r + 12 ≤ 30
