The statement "Nina makes $10 per hour at her second job each week" is true, based on the given expression. The expression 2(10x) 15y represents the money Nina earns in a week. Since y represents the number of hours she works in her second job, and she earns $15 for each hour at that job, it implies that she earns $15 per hour at her second job. Therefore, the statement "Nina makes $10 per hour at her second job each week" is incorrect.
