Let the number of daisies be x;
So number of lilies bought is (20-x)
This means the amount of money spent on daisies is 2x while the amount spent on lilies is 3(20-x).
If total amount spent is 48, then the following equation stands:
2x + 3(20-x) =48
Solving that,
2x + 60 - 3x = 48
X = 12
Hence number of lilies bought is
(20-x) = 8
So number of lilies bought is (20-x)
This means the amount of money spent on daisies is 2x while the amount spent on lilies is 3(20-x).
If total amount spent is 48, then the following equation stands:
2x + 3(20-x) =48
Solving that,
2x + 60 - 3x = 48
X = 12
Hence number of lilies bought is
(20-x) = 8
