1. Knowing that 1000g=1kg, I will convert all the units in g.

She cooked 3530g in 3 days

She cooked 4570g in 3 days

2. I add the values

She cooked 8100g in 6 days

3. I divide the total of grams by the total of days

8100÷6= 1350g per day or 1kg and 350g per day

If we add the two figures up and divide by the number of days she has been cooking the rise, on average she has been cooking 1.35 kg ( 1 kg and 100 grams) a per day, considering from Monday to Saturday.
