【Question 5】
To the left and right of Xiaoming's house, there is a supermarket each having a promotion on the same brand of yogurt. If Xiaoming goes to the supermarket on the left to buy, the money he brings is just enough to buy 12 boxes; if he goes to the supermarket on the right to buy, the money he brings is just enough to buy 2 more boxes. It is known that the price per box of yogurt at the right supermarket is 1 yuan cheaper than that at the left supermarket. How much money did Xiaoming bring in total? $\qquad$ yuan.
【Analysis and Solution】
( Method One )
The price of each box of yogurt at the right supermarket is 1 yuan cheaper than that at the left supermarket;

Therefore, buying 12 boxes of yogurt, the right supermarket is cheaper by $1 \times 12=12$ yuan;

This 12 yuan can buy 2 more boxes at the right supermarket;
Thus, the price of each box of yogurt at the right supermarket is $12 \div 2=6$ yuan; Xiao Ming brought a total of $6 \times(12+2)=84$ or $(6+1) \times 12=84$ yuan.
（Method Two）
Let the price of each box of yogurt at the right supermarket be $x$ yuan, then the price of each box of yogurt at the left supermarket is $(x+1)$ yuan;
According to the problem, we get $12(x+1)=(12+2) x$; solving this gives $x=6$;
Xiao Ming brought a total of $6 \times(12+2)=84$ or $(6+1) \times 12=84$ yuan.
