Answer:
136 kobo
Step-by-step explanation:
total money paid = number of words × rate
in this case she already paid 40 kobo for 12 words and now what remain are the next 48 words for which she have to pay 2 kobo for each word.
therefore she paid 2×48 kobo for 48 words i.e. 96 kobo
then her total sum would be 96+40= 136 kobo.
