Answer:
The net effect of amount in John account after 5 months is $A - $200
Step-by-step explanation:
Given as :
The amount of money withdraws by John each month from his account = $40
Let The total amount of money did John had in his account = $A
Let the amount left in John account after 5 months of withdraw = $x
<u>So, According to question</u>
∵ Each month the money withdraw from account = $40
∴ In 5 months , the money withdraw = $40 × 5
I.e In 5 months , the money withdraw = $200
So, The left money in account after withdraw in 5 months = $A - The amount withdraw in 5 months
I.e x = $A - $200
So, The balance in account after 5 months = x = $A - $200
Hence, The net effect of amount in John account after 5 months is $A - $200 Answer
