Solution:

Given that  

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

They sold the tafty in 400 g bags for

Need to calculate the profit the made.

Cost price of 190 kg of taffy =

As 1 kg = 1000 gram,

So 190 kg of taffy =

So cost price of 190000 gram of taffy =

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

Number of 400 grams bags =

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

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

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
