Question 1133140
.
<pre>
You can solve it mentally.


Let x be the amount which Grace still has after spending her 245 dollars.


Then the amount which Janice still has after spending her 74 dollars is 4x.


The difference, 4x - x = 3x, is equal to the difference 245 - 74, which is 171 dollar (note that you can calculate it mentally !).


Then x = {{{171/3}}} = 57 dollars (and you can calculate it mentally, too !)


Hence, Grace did have initially  245 + 57 = 302 dollars.     <U>ANSWER</U>


<U>CHECK</U>.  302 - 245 = 57;   302 - 74 = 228;    {{{228/57}}} = 4.     ! Correct !

Solved.
