40 people
40 people paid 25 dollars each (40*25=1000)
if you add 10 people then
50 people pay 20 dollars each (50*25=1000)
since 25 is 5 more than 20, this is the correct answer

each 15 seconds. I hate it whilst a set of youngsters or a great relatives stand marvelous in the midst of a motor vehicle parking area or in the midst of the line having a verbal replace. I additionally hate it whilst a baby is appearing out or they save wandering off and the mum and dad do not pay any interest.

n*f = 1,000
(n + 10)(f - 5) = 1,000
nf + 10f - 5n - 50 = 1000
10f - 5n = 50
2f - n = 10
2000/n - n = 10
2,000 - n^2 = 10n
n^2 + 10n - 2000 = 0
n^2 + 10n + 25 = 2025
(n + 5) = 45
n = 40
f = 25
40*25 = 1,000
50*20 = 1,000
