Question

A toy store worker packed two boxes of identical dolls and plush toys for shipping in boxes that weigh 1oz when empty. One box held 3dolls and 4 plush toys. The worker marked the weight as 12 oz. the other box held 2 dolls and 3 plush toys. The worker marked the weight as 10 oz. explain why the worker must have made a mistake.

Answer 1

The total weight of 4 dolls and 3 plush toys is 11 oz

Let's say the dolls weigh 2 oz and the plush toys weigh 1 oz

2-4= 8 1x3 =3

8+3=11

Then 2 dolls =4 and 3 plush toys= 3

Weight should be 7oz

Plus the weight of the box 1

Total= 8 not 10
