Question

The table shows how the amount of Ariel’s bank account changed over several weeks.

Answer 1

Explanation:

I guess the missing values are in the non-shaded cells.

Filling in by rows:

Week 3

182.35 - 337.50 = -155.15 (it was right)

Week 4

-41.40 - 182.35 = -223.75 (it was wrong)

Week 5

-41.40 + 40 = -1.40 (it was wrong)

Week 6

-5.80 - (-1.40) = -4.40 (it was wrong)
