Janet spent 30% of her money on 7 cupcakes and 4 cookies on Monday. The cost of each cupcake was twice the cost of each cookies. She bought some more cupcakes and another 10 cookies with 6/7 of her remaining money on Tuesday. How many cupcakes did she buy on Tuesday?

(7*2)+4=30% of money

18=30% of money

60=100% of money

6/7 of 70%= 60%

60%=36 cookies

(36-10)/2=13
