At the garden centre there are 17 different types of shrubs and some rose trees.

You must show how you get your answer. (2)
| Answer | Mark | Notes |
|---|---|---|
| No (supported) | P1 | Process to find number of rose trees e.g. \(215 \div 17\ (= 12.647\ldots)\) or show number of choices with 12 and 13 eg \(17 \times 12 = 204\) and \(17 \times 13 = 221\) |
| C1 | No with interpretation that 12.6.. is not a whole number or a whole number of plants must be bought or number of plants would have to be between 12 and 13 which is not possible |
