Answer:
5 kids
Explanation:
Given in the question,
amount charge per day = $25
amount spend on each child = $5
amount earn on each child = 25-5 = $20
Suppose total amount each day she need x
x(20) = 2000
x = 2000/20
x = $100
number of kids per day = total money each day / money on each child
= 100/20
= 5
