Answer:
400
Step-by-step explanation:
2600-1000=1600 1600/4=400
John account increases at a rate of change of $400 per month.
" Rate of change is defined as the change is observed in one quantity with respect to another quantity."
Formula used
Rate of change in account
[tex]Rate of change = \frac{Change in amount }{Change in time }[/tex]
According to the question,
John account has,
Initial amount in month of February = $1000
Final amount in month of June = $2600
Change in amount = Final amount - Initial amount
= $2600 - $1000
= $1600
June represent 6th month
February represent 2nd month
Change in Month = 6 - 2
= 4months
Substitute the value in the formula of rate of change we get,
Rate of change = [tex]\frac{\$1600}{4}[/tex]
[tex]= \$400 per month[/tex]
Hence, John account increases at a rate of change of $400 per month.
