Narda has $250 and Ding has $170. How much money must Narda give to Ding so that each of them will have an equal amount of money?

Find the difference of Narda and Ding's money:
Difference = Narda - Ding
Difference = 250 - 170
Difference = 80

Find half the difference:
Half the difference = 80/2
Half the difference = 40

So Narda must give Ding $40 to have equal amounts:
Narda's new total = 250 - 40 = 210
Ding's new total = 1760 + 40 = 210
