to figure the difference in time, calculate the number of hours she would have to work at each rate and subtract the two.
$500=X1 Hours * $6.25/hour
$500=X2 hours * $7.00/hour
by figuring hours as your units, and multiplying by a value with the units $/hour, the hours cancel out and you should get $.
You can take these equations and divide both sides by the $/Hour number to get the following equation:
$500/(6.25 $/hour) = X1 hours
Hope this helps.
if you divide 500 by 6.25, you will get the number of hours required at 6.25 an hour
