They made profit of $\ 834.10$ by selling 190 kg of taffy in 400 g bags at rate of $\ 3.28$ each.

Solution:

Given that  

To raise money, the Boy Scouts bought 190 kg of taffy for $\ 723.90$.

They sold the tafty in 400 g bags for $\ 3.28\text{ each }$

Need to calculate the profit the made.

Cost price of 190 kg of taffy = $\ 723.90$

As 1 kg = 1000 gram,

So 190 kg of taffy = $190\times 1000 = 190000\text{ grams of taffy }$

So cost price of 190000 gram of taffy = $\ 723.90$

Now let us calculate number of 400 grams bags which can be made from 190000 grams of taffy

Number of 400 grams bags = $\frac{190000}{400}=475 \text { bags }$

Amount generated from 1 bag of 400 gram taffy = 3.28

So amount generated from 475 bags of taffy = $475\times3.28 = \ 1558$

Selling price of 190000 grams of taffy = amount generated from 475 bags of taffy = $\ 1558$

$\text{ Profit }= \text{ selling price }-\text{ cost price }= 1558-723.90 = \ 834.10$

Hence they made profit of $\ 834.10$ by selling 190 kg of taffy in 400 g bags at rate of $\ 3.28$
