Question 1195141
<br>
Somewhere in his analysis the other tutor made a mistake....<br>
The purchase price was p; the amount of change Javonne originally received was c.<br>
Since the situation was corrected by returning $1 to the cashier, the correct change was c-1.<br>
The purchase price was twice the original amount of change, so p=2c.<br>
The purchase price, plus the corrected amount of change, was $20:<br>
{{{p+(c-1)=20}}}
{{{2c+(c-1)=20}}}
{{{3c-1=20}}}
{{{3c=21}}}
{{{c=7}}}<br>
The purchase price was 2c = $14.
The original amount of change was c = $7.
The correct amount of change was c-1 = $6.
The purchase price plus the correct amount of change was $14 + $6 = $20.<br>
ANSWER: c, the original amount of change, was $7<br>
