We know that the prices of the clothing are
Shirt $23
Belt $9
Sweater $38
Pair of Jeans $42
And we must find how much money Ming spent if Ming bought 8 belts.
Since Ming bought 8 belts we can find the money spent multiplying 8 by the cost of one belt
In order to make the multiplication more easy we can rewrite 8 as 4*2
Finally, the money spent will be
[tex]4\cdot2\cdot\text{ \$9= \$72}[/tex]So, Ming spent $72
