For this case, the first thing we must do is define a variable.
We have then:
x: number of weeks
y: amount of cereal that Melanie eats
We now write the function that models the problem:
[tex]y = 1.5x
[/tex]
Then, for 5 weeks we have:
[tex]y = 1.5 (5)
y = 7.5 pounds[/tex]
Answer:
A model that best represents the number of pounds of cereal she eats is:
[tex]y = 1.5x
[/tex]
For 5 weeks we have:
[tex]y = 7.5 pounds[/tex]
