On Tuesday, Liza had $800 in her checking account. On Wednesday, she paid her rent, $450. On Thursday, she deposited her $1500 paycheck. On Friday, she paid her electricity and internet bills which were $117 and $100, respectively. Then on Saturday, she paid her phone bill, $70. How much money is left in Liza's account?
Thoughts? Step-by-step reasoning:
On Wednesday, Liza had $800 - $450 = $350 left in her account. After depositing on Thursday, she had $350 + $1500 = $1850 in her account. On Friday, she paid a total of $117 + $100 = $217 for her electricity and internet bills. So, $1850 - $217 = $1633 was left on her account on Friday. After paying her phone bill, Liza has $1633 - $70 = $1563 left in her account.
Thus, the answer is 1563.
