Answer: $15
Step-by-step explanation:
8 cookies cost $12 you divide 12 by 8 and then you get 1.5 which equals 1.50 so each cookie is 1.50. So for 10 cookies you multiply 10 times 1.50 and you get your answer $15. 10 cookies cost $15

The Y is multiplying by 2 across the X OR the X’s are being divided by 2
Ex: 3x2=6 OR 6/3=2
