The irrational numbers are √10,√27,√99.
Do you mean scientific notation
28+24=52
So we make a sum of what's going to equal 52 in small packets.
I found 4x13=52. 13 would be the number of packets......
BUT!! Since it MUST be equal dark and milk and we have 28 and 26,
you would have to eliminate 1 pack because all 4 would be milk chocolate.
So that is only 12 packets.
4 per pack so that would be 2 dark and 2 milk per packet.
1. Find the unit rate
15 books divided by 5 days = 3 books sold per day.
Since we are looking for how many days it would take the store to sell 21 bucks, we could do 21 (amount of books) divided by 3 (how much books is sold in a day).
Therefore, it will take a week / 7 days to sell 21 books.
he saves $860 per month
calculate each of his outgoings
rent = 
× $3600 = 
= $900
food = 
× $3600 = 
= $1440
activities = 
× $3600 = 
= $400
savings = $3600 - ( 900 + 1440 + 400 ) = $860
