Answer 1

0.14g

Explanation:

Anna is preparing 30 days of desert for her pet beetle.

She starts by mixing 3.67g of pureed ants with a 1.43g blueberry.

She then divides the mixture into 30 equal parts, one for each day.

The international federation of beetle should have 0.15g of such a dessert each day.

For each day Anna's pet eat:

`(3.67 + 1.43)/(30) = 0.17`g

For seven days, the pet will have eaten;

0.17g × 7 = 1.19g

The international federation require that a beetle should eat;

0.15g × 7 = 1.05g

So Anna's beetle will have eaten 1.19g - 1.05g = 0.14g more than the recommended amount.
