Question

Melanie eats 1.5 pounds of cereal each week. Which model below best represents the number of pounds of cereal she eats in .5 weeks?

Answer 1

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:

`y = 1.5x`
Then, for 5 weeks we have:

`y = 1.5 (5) y = 7.5 pounds`
Answer:
A model that best represents the number of pounds of cereal she eats is:

`y = 1.5x`
For 5 weeks we have:

`y = 7.5 pounds`
