Answer:

8 months

Step-by-step explanation:

The question asks for the minimum number of months it would take her to grow her hair ATLEAST 16 cm.

Lets solve this!

Her hair is ALREADY 4 cm

She needs to make it 16 cm or greater

That is:

16 - 4 = 12 cm MORE

Per month growth rate = 1.5 cm

So we will divide the amount she needs to grow (atleast) by the growth rate per month:

12/1.5

= 8

Thus, in 8 months, her hair will grow:

8 * 1.5 = 12 cm

and 4 cm from before, so

12 + 4 = 16 cm

So, it will take a minimum of 8 months
