Answer:
Maureen makes $11 an hour and Karl makes $10.
Explanation:
We can start by making an equation. We know that they both worked 40 hours. So we have the time and let the amount she is payed be x. We know Maureen is payed $1 more, so we also add that to the equation.

After releasing the parenthesis, this is our equation:

After adding 40x and 40x together and subtracting 40 from both sides:

Divide by 80:

We are still not done. We know how much Karl makes now, and we add 1 to Karl's salary to get Maureen's.
