Can someone pls help me with this question?

d

Step-by-step explanation:

the slope from month 4 to month 5 is positive so the money in his account is rising

D. The bank balance in John's saving account increases from Month 4-5

Step-by-step explanation:

Lets go with one answer at a time

However, an entire $750 has changed therefore, option A would be incorrect.

When in fact it has changed more than $250 downwards, so option B would be incorrect.

However, in that time period it stays the same therefore, option C would also be incorrect.

Now that should mean that D is the right answer, but, we should still check.

Yes it does change upwards. It increases $750 again.

Therefore, your answer would be D. The bank balance in John's saving account increases from Month 4 to 5.
