Question

A. 200
B. 250
C. 300
D. 350

Answer 1

Fiona uses C) 300 blueberries.

Step-by-step explanation:

To find out how many blueberries Fiona uses, we need to set up a ratio between the number of blueberries Mike uses and the number Fiona uses. We know that for every 30 blueberries Mike uses, Fiona uses 50. Let's assume that Fiona uses x blueberries. Now we can set up the following ratio:

(30/50) = (400/x)

Cross multiplying, we get 30x = 50 * 400. Solving for x, we find that Fiona uses 400 blueberries. Therefore, the answer is C. 300.
