Givens

We know that Morita arranges 4 cases, each of them has 10 flowers.

So, if there are 2/10 daisies per case, that means each can contains 2 daisies.

But, she did 4 arrangements. There are 2x4 = 8 daisies in total.

Now, last weekend, Morita used 10 daisies to make flower arrangements, and we know she tend to use 2/10 of the flowers as daisies, that means this fraction represents daisies,

Therefore, there are 50 flowers in total.

the answer is ! ?
