Answer: Our weekly paycheck = $385. Our coworker’s weekly paycheck = $442.75.
Explanation:
Let’s find how much money we got from one of the two paychecks: 2x = 770. (x can represent the amount of money we get from each paycheck.)
2x = 770.
x = 385.
Our weekly paycheck gives us $385.
Now, we can find how much money our coworker gets. Since they earn 15% more money than us, we add 15% to how much money we get from each paycheck: 385 + 15%(385) = y. (y can represent the amount of money our coworker gets.)
385 + 15%(385) = y.
385 + 0.15(385) = y.
385 + 57.75 = y.
442.75 = y.
Our coworker’s paycheck gives them $442.75.
