Elaine had m dollars in her checking account. on december 8, she deposited $1,200, r dollars, and $568.90. she also cashed a check for t dollars and one for $73.70. write an algebraic expression that represents the amount of money in her account after the transactions.

Initial amount in Elaine's account = m dollars (1)

On December 8, total money deposited by Elaine = 1200 + r + 568.9

= r + 1768.9 (2)

Total money on her account now = m + r + 1768.9

Total money she cashed by cheques = t + 73.7.

Therefore, her current balance in her account = (m + r + 1768.9) - (t + 73.7)

= (m + r - t) + 1695.2.

Hence, the algebraic expression that represents the amount of money in her account after the transactions is (m + r - t) + 1695.2.
