Question

A landscaper is planting a tree that is now 55 cm tall. The tree will grow 2 cm per month for x months. The tree will grow to be at most y cm tall. Write an inequality showing this relationship.

Answer 1

Case: Inequality expressions

Method:

Initial height of tree = 55cm

Rate of growh = 2cm per month for x months i.e. 2x

Maximum height = y cm

Inequality expression:

With 'at most' meaning 'less than or equal to'

`55+2x\leq y`

Final answer:

`55+2x\leq y`
