On your math quiz, you earn 5 points for each question that you answer correctly. In the equation below, x represents the number
of questions that you answer correctly on your math quiz, and y represents the total number of points that you score on your quiz. The relationship between these two variables can be expressed by the following equation:
y=5x
Identify the dependent and independent variables.
Dependent variable
Independent variable
The total number of points you score
The number of questions you answer correctly
Dependent variable: y because you get the points by doing the quiz. Independent variable: x because you don’t know how many questions you answered correctly. Total points you score: Unknown until you know how many you got right also the same as y. Number of questions you answer correctly: Unknown until you get your paper back, also the same as x.
You practically answered this one yourself by giving some of the equation we need already filled in. It would look like this: A(t)=500(1.04)^7. Start by taking 1.04 to the power of 7 to get A(t)=500(1.3159). Finish by multiplying to get A(t)=$657.97
