OpenStudy (anonymous):

bc the first week they have 45 , then if u add 5 times 5 it is 120 which is what they need... correct?

OpenStudy (anonymous):

15 times 5**

OpenStudy (skullpatrol):

Subtract 45 off of 120.

OpenStudy (anonymous):

75

OpenStudy (skullpatrol):

That^ is what they need

OpenStudy (skullpatrol):

Divide 15 into 75

OpenStudy (anonymous):

5

OpenStudy (skullpatrol):

They want at least 120.

OpenStudy (texaschic101):
