Tom needs to save some money to buy himself a new car. At the start of January there is $400 in his savings account. He is able to add $100 to the account at the end of each month.In April he knows that he will be paid a bonus and have an increase in his salary, so he needs to add $500 to his account at the end of April and then $150 each month of that.Which of the following graphs represents the total money that he will share in his savings account at the end of each month?
Correct answer: A. A
- A. A
- B. B
- C. C
- D. D
Explanation
The correct answer is Option A. This graph correctly represents the total amount in Tom's savings account at the end of each month by including his initial balance, monthly contributions, and additional contributions in April and subsequent months. The other options do not consider all the contributions accurately, leading to incorrect representations of the total amount in Tom's savings account.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.
