First, figure out how much she'll earn per min. .004 x 90 = $0.36 per min
$0.36 x 60 min/hr = $21.60 per hr
A.
Need to hit $1,000 for breakeven:
21.60h = 1000
h = 46 hrs for breakeven
B.
4 hrs/day x 3 days = 12 hrs total per week Then 4 weeks in a month means she worked 48 hrs that month.
Set up polynomial equation with e as earnings:
48h = e
48 x 21.60 = e -- We knew h from the beginning part when we found her hourly rate
$1,036.80 = e
H is the independent variable here since her hourly rate won't change. E is the dependent variable because it changes with the number of hours she works.
