Mr. Hughes is competing in the Mr. Legs campaign to raise money for the Coral Shores High School scholarship fund. On the first day, he collected 2 dollars. On the third day, he collected $8. Let D represent each collection day and N represent the number of dollars collected on that day. Matt claims that the situation can be modeled by an exponential function. Emily disagrees and claims that the number of dollars collected can be modeled by a linear function.

Question

Mr. Hughes is competing in the Mr. Legs campaign to raise money for the Coral Shores High School scholarship fund. On the first day, he collected 2 dollars. On the third day, he collected $8. Let D represent each collection day and N represent the number of dollars collected on that day. Matt claims that the situation can be modeled by an exponential function. Emily disagrees and claims that the number of dollars collected can be modeled by a linear function.

Which statement is true about the number of dollars predicted to be collected on the 6th day based on the two models?

The number of dollars predicted to be collected on the 6th day using an exponential model is less than that predicted using a linear model.
The number of dollars predicted to be collected on the 6th day using an exponential model is greater than that predicted using a linear model.
The number of dollars predicted to be collected on the 6th day using an exponential model is equal to that predicted using a linear model.
There is not enough information to determine the relationship between the amount of money predicted to be collected on the 6th day using an exponential model and that predicted using a linear model.

Answer 1

The correct answer is: There is not enough information to determine the relationship between the amount of money predicted to be collected on the 6th day using an exponential model and that predicted using a linear model.
