Lisa has a certain amount of money. She spent 39 dollars and has 3/4th of the original amount left. How much money did she have originally



Answer :

$156, $39 is 1/4 of the money so 39 * 4 = 156
If [tex]\frac { 3 }{ 4 } [/tex] is left, that means [tex]\frac { 1 }{ 4 } [/tex] was spent. So [tex]\frac { 1 }{ 4 } [/tex] of the total amount is equal to 39.. Let's say x to the total amount. [tex]\frac { 1 }{ 4 } \cdot x=39\\ x=4\cdot 39\\ x=156\\ [/tex]
