He went home with 72 marbles after tripling his stock. That means he had 72/3 = 24 before school ended.
<span>If he lost half at lunch, he had 24 * 2 = 48 before lunch. </span>
<span>During the third break, he increased he stock by 1/3. That means that 48 = 4/3 * x, so he had 36 before the third break. </span>
<span>During the second break he lost 4, so before he had 36 + 4 = 40. </span>
<span>During the first break he doubled his marbles, so before he had 40 / 2 = 20.</span>

Teen depression is a serious mental health problem that causes a persistent feeling of sadness and loss of interest in activities. It affects how your teenager thinks, feels and behaves, and it can cause emotional, functional and physical problems. Although depression can occur at any time in life, symptoms may be different between teens and adults. Issues such as peer pressure, academic expectations and changing bodies can bring a lot of ups and downs for teens. But for some teens, the lows are more than just temporary feelings — they're a symptom of depression.
Teen depression isn't a weakness or something that can be overcome with willpower — it can have serious consequences and requires long-term treatment. For most teens, depression symptoms ease with treatment such as medication and psychological counseling. Teen depression signs and symptoms include a change from the teenager's previous attitude and behavior that can cause significant distress and problems at school or home, in social activities, or in other areas of life.
