Answer is H because every 2 hours she earns 50 dollars, so you'd divide 50 by 2 or do a proportion for example Hours over money earned: 2/50... then hours over money earned again 1/X... over X because you don't know the amount she earns then you cross multiply. 50×1 that is 50 lol then 2•X that would give you 50/2X then isolate the variable by dividing both side by 2 and 50 divided by 2 is 25
