For this case, the first thing we must do is define variables.
We have then:
x: number of hours
y: Amount of scarf that Sara knits
We then have the following equation that models the problem:
The number of hours during the 8 days is given by:
Substituting the value of x in the ada equation we have:
Answer:
she will knitted by the end of the trip about 52528mm of scarf
Correct Option is:
Two quantities are proportional if we can write one of them as k times the other. In other words, if x and y represents quantities, then if they stands for a proportional relationship we can write:
In whose case, we will have a linear function with slope k and that passes through the origin. From the options, the only one that matches our definition is Option D.
So correct Option is:
