Question 1169090
<font color=black size=3>
Answer: 25 nights
(or 25 days, depending on how you view the problem)


---------------------


Work Shown:
x = number of nights babysitting
1 night = 40*1 = 40 dollars
2 nights = 40*2 = 80 dollars
3 nights = 40*3 = 120 dollars
and so on


In general,
x days = 40x dollars


Meaning we can say 
40x = 1000
x = 1000/40
x = 25


Bonita will need to babysit for 25 nights to earn $1000 total.
