Jack wants to buy an electric guitar. he began the the year with some money saved to buy the guitar, and each week he adds a fixed amount to his savings. if y represents the total amount jack has saved after x weeks, which of the following situations is represented by the table below?

a. jack initially had $45 saved, and the amount is increasing at a rate of $15 per week.
b. jack initially had $45 saved, and the amount is increasing at a rate of $30 per week.
c. jack initially had $75 saved, and the amount is increasing at a rate of $15 per week.
d. jack initially had $75 saved, and the amount is increasing at a rate of $30 per week.

For this case it can be seen that in the table, the values of "x" represent the number of weeks Jack has saved. The weeks are represented two by two.

On the other hand, the values of "y" represent the amount of money saved by Jack in relation to a certain week "x".

We note that in week 2 Jack had $ 75, in week 4 he had 105.

This means that in two weeks I add to your savings:

$

We also observed that he adds $ 30 every two weeks.

Then the option that best fits is:

Jack initially had $ 75 saved, and the amount is increasing at a rate of $ 15 per week.
