Let x be the amount of money that Maria makes.
Let 2x be the amount of money that Joan makes

Together they make $40

x + 2x = 40
3x = 40
x = 40/3
x = 13 1/3

Hmm…

Did you get something wrong?

If Maria made $8, then they would make $24 total
If Maria made $10, then they would make $30 total
If Maria made $12, then they would make $36 total
If Maria Made $14, then they would make $42 total

Did you mean $42?

Answer:
None of the above ($13.33), but the closest answer is $14.
