Answer 1

She needs to earn at least 84 to buy the mp3 player

earnings=earningsperhour times numberofhoursworked

earnings per hour=12 dollars
number of hoursworked=h

therefor
earnings=12 ties h or12h

earnings is at least 84
earnings is greater than or equal to 84
earnings>84
12h>84

solve
12h>84
divide both sides by 12
h>7
she needs to work at least 7 hours
