Jenna has $1500 in a savings account. she adds $30 to her account each month. luis has $2400 in his savings account. he withdraws $30 from his account each month. a. in how many months will they have the same balance in their savings accounts

15 months

Explanation:

Jenna's account balance = $1500

Addition to account for x number of months = $30

Total deposits = 30x

Luis's account balance = $2400

Withdrawal from the account for x number of months = $30

Total withdrawal = -30x

For both accounts to be the same

1500 + 30x = 2400 - 30x

30x + 30x = 2400 - 1500

60x = 900

x = 900/60

x = 15

In 15 months, the savings accounts of both of them will have the same balance.

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."

hope this : )
