Answer:
a = $ 18
Step-by-step explanation:
It is given that Chinase's allowance is $6 per week and it is 1/3rd of his brother's allowance. Assuming the brother's allowance as "a", we can write the equation as follows:
[tex]\$6 = \frac{a}{3}\\a = (\$6)(3)[/tex]
a = $ 18
Therefore, the allowance earned by Chinse's brother every week is found to be $ 18.
