Q. Jimmy receives his first 3 video games free then pays $50 for each game after that.Is the amount of money he spends on video games proportional to the number of games he owns?Choose 1 answer:(A) Yes(B) No
Define Variables: Let's define the variables:- Let x be the number of video games Jimmy owns.- Let y be the amount of money Jimmy spends on video games.According to the problem, Jimmy receives his first 3 video games for free. This means that for x=3, y=0. After that, for each additional game, he pays $50. This means that for every game beyond the first 3, the cost increases by $50.To determine if the relationship is proportional, we need to see if there is a constant rate of change between x and y. A proportional relationship would mean that for every increase in x, there is a constant increase in y.Let's calculate the cost for the 4th game:For y2, Jimmy has to pay for y3 game, so y4.Now, let's calculate the cost for the 5th game:For y5, Jimmy has to pay for y6 games, so y7.We can see that the amount Jimmy pays does not increase by a constant amount for each additional game because the first 3 games are free. The relationship between the number of games and the amount spent is not constant from the start; it only becomes constant after the first 3 games.
Calculate Costs: To further illustrate why this is not a proportional relationship, let's consider the definition of a proportional relationship. A proportional relationship is one where the ratio of one quantity to the other is constant. In this case, the ratio of the amount spent to the number of games owned should be constant if the relationship is proportional.For the first 3 games, the ratio y/x would be 0/3=0. For the 4th game, the ratio would be 50/4. For the 5th game, the ratio would be 100/5=20. The ratios are not the same, which means the relationship is not proportional.
