Question
Answer:
she wanted to buy 6 bottles. the cost of 10 bottles was $12.
therefore we need to find the cost of one bottle and then find the cost for 6 bottles.
if 10 bottles cost - $ 12
then 1 bottle costs - $ 12 / 10 bottles
here we divided 12 by 10 , cost of 1 bottle is 12/10 to find the cost of 6 bottles we have to multiply by 6 .12 / 10 x 6
correct answer is therefore B. divide 12 by 10 and then mulitply by 6
