Question

Meg is starting a day-care center for the people in her community. She decided to charge $25 per day per child, out of which $5 is her expenditure per child per day. If Meg's target is to earn $2,000 over 20 weekdays in June, the minimum number of kids she has to watch per weekday that month is

Answer 1

If I figured correctly it is 5 kids. Sorry if wrong!

Answer 2

5

Explanation:

Let the number of kids be x

We are given that she charge $25 per day per child

So, she charge for x kids per day = $25x

So,charge for x kids for 20 days =
`20 * 25 x = 500x`

Her expenditure per day per kid is of $5

So, her expenditure per day for x kids = $5x

So, her expenditure 20 days for x kids =
`20 *5 x = 100x`

So, she gained for taing care of x kids for 20 days = 500x-100x = 400x

Since we are given that her target is to earn $2000

So, A.T.Q

`400x= 2000`

`x= (2000)/(400)`

`x=5`

Hence the minimum number of kids she has to watch per weekday that month is 5
