The cost is $3.75 per gallon. I think that the correct answer for your second question is .307 gallons per dollar.
Unit rate is total price divided by total quantity:
Unit rate = 6.60 / 12
Unit rate = 0.55 each
1.50 x 7 = 10.5
0.85 x 5 = 4.25
10.5 + 4.25 = 14.75
So you can only have 7 roses . I found this out using trial and error and then adding on the correct number of carnations to make it a dozen and to make sure it equaled 14.75 .
Hope this all makes sense .
