Question

Can someone check to see if my answer is correct?
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 5 kids per day.
I say 5 because its 20 days and she need to make at least $100 a day to make $2000.
But I'm not sure if it's a trick because it says weekdays and not sure if weekdays change on the calendar year to year.

Answer 1

@Michele_Laino can you help please?

Answer 2

I think that every day Meg has to pay $25 per child, so, if I call with N, the number of children which Meg has to care about every day, then every day she spends 25*N

Answer 3

so we can write:
\[25 \times N \leqslant 2000\]

Answer 4

but it costs her $5 per day per child so she is only making $20 per child

Answer 5

N would be less than or equal to 80

Answer 6

sorry, N would be 80, in only 1 day. We have to consider a time period of 20 days, so we have:
\[25 \times N \times 20 \leqslant 2000\]

Answer 7

since Meg spends, in total, $25 per child, and she has only $2,000

Answer 8

ok so 4 but shouldnt read
20*N*20 less than or equal to 2000
because you need to deduct $5 expenditure per child

Answer 9

yes! $25 in total

Answer 10

" She decided to charge $25 per day per child, out of which $5 is her expenditure per child per day."

Answer 11

that $5 isn't needed?

Answer 12

yes! I think that Meg has to charge $20 per child + $5 per expenditure of each child, so in total $25 per child

Answer 13

ok so I misunderstood the question. so the answer is 4 children perday for 20 days. yes?

Answer 14

yes! I think so!

Answer 15

ok thank you!!!

Answer 16

thank you! :)

Answer 17

@radar can u check this answer. The $5 expenditure leads me to believe she will only make $20 per day per child

Answer 18

if there are 4 children your answer is correct

Answer 19
