Question

Johnathan can spend at most $30 at the amusement park. It costs $12.00 for admission and each ride costs $3.00. Which inequality shows the number of rides that Johnathan will be able to ride at the amusement park? PLS HELP

Answer 1

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
