2) The florist sold at least 95 roses.

Thus, the total number of roses sold = x + 12y.
Given: Total sales = 2x + 19y
We have to get the value of x + 12y.
Let's take each statement one by one.
1) The florist made $190.
2x + 19y = 190.
x = (190 - 19y)/2
x = 19(10 - y)/2
y can have any value from 2, 4, 6, and 8; thus, accordingly, x will have respective values. No unique value of x + 12y. Insufficient.
2) The florist sold at least 95 roses.
Certainly insufficient.
(1) and (2) together
From x = 19(10 - y)/2:
@y = 2, we have x = 19(10 - 2)/2 = 76; thus, x + 12y = 76 + 12*2 = 76 + 24 = 100 ≥ 95. The number roses sold can be 100.
@y = 4, we have x = 19(10 - 4)/2 = 57; thus, x + 12y = 57 + 12*4 = 57 + 48 = 105 ≥ 95. The number roses sold can be 105.
No unique value of x + 12y. Insufficient.
The correct answer: E
Hope this helps!
