Objective #5: Solve applied problems using formulas. Solved Problem #5 Pencil Problem #50 5. It has been shown that persons with a low sense of 5. The formula C =1388x +24,963 can be used to humor have higher levels of depression in response to model the cost, C, x years after 1980 of what cost negative life events than those with a high sense of $10,000 in 1967. Use the model to determine in humor. This can be modeled by the following which year the cost will be $77,707 for what cost formulas: $10,000 in 1967. Low-Humor Group: D =- 10 53 High-Humor Group: D = 26 9 where x represents the intensity of a negative life event (from a low of 1 to a high of 10) and D is the level of depression in response to that event. If the low-humor group averages a level of depression of 10 in response to a negative life event, what is the intensity of that event? Low-Humor Group: D = 10 53 9 10= 10 53 9.10=9 10 53 9 90 = 10x +53 90-53=10x+53-53 37 = 10x 37 10x 10 10 3.7 =.x x =3.7 The formula indicates that if the low-humor group averages a level of depression of 10 in response to a negative life event, the intensity of that event is 3.7
