Question

Tori Chang and her cousin, Sumi decide to open an accounting business. They will need a total of $60,000 to get the business started. Sumi has spent a lot of time getting the business set up, so Tori agrees to contribute $8,000 more than Sumi. How much money will Tori contribute?

Answer 1

Tori will contribute 8000/2 more than half of the total, so $34,000.

_____
If you want to solve equations, let t and s represent Tori's and Sumi's contributions.
.. t + s = 60000
.. t - s = 8000
Add the two equations
.. 2t = 68000
.. t = 34000 . . . . . . divide by 2 to find t
