Answer:

26h + 30

Explanation:

First, I added the expressions together, simply 12h + 50 + 14h - 20

Second, I put the like terms next to each other, and got 12h + 14h + 50 - 20

Third, I combined them to get my final answer, 26h + 30

Hope this helps ;)

Answer:

26h + 30

Explanation:

Summing up the two earning amounts, we get:

12h + 50 + 14 h - 20,

which simplifies to

26h + 30

This is the total dollar amount earned, where h is the number of hours worked by both people.
