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<u>></u>84
12h<u>></u>84
solve
12h<u>></u>84
divide both sides by 12
h<u>></u>7

Answer:
5 children
Step-by-step explanation:
$7.31 x2 = $14.62
$46- 14.62 =$32

5.66 divided by 6 = 33
and $33 is bigger than $31

F/45 - 2/9 = 2/9....add 2/9 to both sides
f/45 = 2/9 + 2/9
f/45 = 4/9 ...multiply both sides by 45
f = 4/9 * 45
f = 180/9
f = 20 <===
