Ok since Sarah deposited four 125.25 paychecks she has $501 dollars in her bank to spend this is because 125.25 x 4= 501 , then sarah makes four withdrawls each withdrawl is for 45 dollars 45 x 4= 180 then sarah withdraws 400 dollars so if you add all her withdrawls together 400+180=580 so she has spent 580 dollars she had 501 in her account to spend so 580-501=79 this is wrong because she is negitive but taking the highest number and subtracting the smaller one is easier so she has -79 dollars in her account
⇔ x = 16
