Answer:
The answer is -4.5
Step-by-step explanation:
according to my calculation
156/12 = 12 * 13/12 = 13 :D
If you mean the x, it would be 50
So 22% off means that the shoes cost 100-22=78%
the shoes cost $42 so
42=78%
we want to find how much is 100% so we multiply 42/78 by 100/x where x is the cost since the same fraction inverted and multiplied by itself is = to 1. (if you don't get this feel free to message me)
so 4200/78x
we divide this on a calculator and get $53.85
