Let price of a sundae = S
Price of ice cream bar = .6 $

125 * .6 + 125*S = 200
=> 125*S = 125
=> S = 1

Answer C

We can also solve this using weighted average .
Since the number of ice cream bars and sundaes are same .
Total average price per ice- cream and sundae = 200/ 250 = .8

And we know that price of ice cream bar is .6 $ which is .2 $ below the average price .
Therefore , price of sundae will be .8+.2 = 1 $

Answer C
