Yusuf Nelson · Answer 1

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
