i think its -7.95

OpenStudy (dtan5457):

You think it's a negative number?

OpenStudy (dtan5457):

Since he buys the SAME coffee everyday, that means there must a set rate or price per day.

OpenStudy (dtan5457):

From day 4-5 18.20-15.25=?

OpenStudy (dtan5457):

That will give the price of a coffee each day.

OpenStudy (dtan5457):

Hmm? How'd you get that?

OpenStudy (anonymous):

oops

OpenStudy (anonymous):

OpenStudy (dtan5457):

Good, now you have the rate. 15.25-2.95, and you get the amount for day 6.

OpenStudy (anonymous):

12.3
