Tom is saving $3000. He deposits $200, then a fixed amount every month for 5 months. Then gets a check for 3 times the total amount saved so far. When depositing the check, he now has $400 extra. What was the fixed amount deposited each month?

This is an algebra sum and can do it for you :)

Do you know how to solve it? Can you show me?

Yes I can show you work. Let me do it on paper

Hello? Are you still there?

Let the amount he saved per month be $ x

So, for 5 months he deposits $5x

before he deposited $200 , so now he has saved $200+5x

now he gives a check for 3 times of total amount saved so far. so check value = 3 * (200+5x) = 600+15x

now he has got $400 eextra = $400 + 3000 = $3400

so 600+15x+200+5x = 3400

=> 800 + 20x = 3400

=> 20x = 3400 - 800

=> 20x = 2600

=> x = 2600/20 = 130

So per month he saved $ 130 (ans )

best the answer :)

Perfect, it checks correctly! Thank you!

So, please best the answer :)
