In the second grade, they practiced math at the same time. How much did they spend each? Biscuits 3 yuan, Xiaoming bought three bags, sandwiches 6 yuan, Xiaojun bought five pieces, milk 5 yuan, and Xiao.
Xiao Ming: I bought 3 packets of biscuits, each packet of 3 yuan, which means 3×3=9 yuan.
Xiaojun: I bought five sandwiches, each 6 yuan, which means 5×6=30 yuan.
Xiaohong: I bought two boxes of milk, each box of 5 yuan is 5×5= 10 yuan.
Obviously, Xiaojun has more money and can eat more. . . .
They spent 9+30+ 10=49 yuan.
