Question

Luna’s saving increases as a linear function of the number of chores she does, as shown in the table. How much money did Luna have saved before she started doing chores?

Answer 1

The Answer is 70

Explanation:

This is because in the text it states that Luna’s saving increases so that means that each time she does a chore it increases by 4.

Answer 2

$70.

Explanation:

From the table shown in the image, we see that for each chore, savings is increased by $4. So, each chore values $4.

Now, if after the first chore she has $74, this means that before it, she had $70, because each one increase by $4 her savings.

Therefore, the answer is $70.
