Total money earned by Juan = 3w-6
Now Juan saved 1/3 of the money.
So money Juan spent will be 2/3 of what he earned.
Money Juan spent :
[tex] \frac{2}{3} (3w-6) [/tex]
Simplifying we get :
2w-4
Emma wrote the expression as 2(3w-6) which is not equal to 2w-4.
So we can say that the expression found by Emma was incorrect .
