Answer:
You go to whoever's question you wanna answer and it should say "add answer" and just type out your answer and solve it
Interest earned = rate charged × amount invested
Interest = 3/100 × $3000 = $90
Account balance after one year = Amount invested + Interest earned
Account balance after one year = $3000 + $90 = $3090
The next two numbers are 0.24 0.36 Your just adding 0.06.
Hope this helped you!
