Question

Anna bought a box of blueberries for £7. She used 700 grams for a cheesecake and she has 450 grams left. How much did the blueberries cost per 100 grams?

Answer 1

0.61 (rounded up)

Step-by-step explanation:

You add both 700 and 450 which will give you 1150g

You then divide 1150 by 100 which gives you 11.5

Then divide 7 by 11.5 which will give you 0.61 as cost of every 100 grams
