Question 906473
 the amount is {{{n}}}

after Joan withdrew  $ {{{ 45.00 }}} from her checking account, we have {{{n-45.00}}}


 since her balance is ${{{32.50}}}, we have {{{n-45.00=32.50}}}


 

{{{ n-45.00=32.50 }}} solve for {{{n}}}

{{{ n=32.50+45.00 }}}

{{{ n=77.50 }}} ....the amount in her account before she made the withdrawal was ${{{77.50 }}}
